Mysterious 'glitch' being unable to READ emails!
It has usually been very good and a 'must' for me (passwords saved securely for me to just 'click into' other sites). I do like & need the feature 'saved passwords' or I really ought to have them down in hand-writing kept in a secure place. Also, on occasions Firefox has prevented me getting into certain, perhaps risky, sites. LAST WEEK WASTED LOTS OF TIME, though, and NO responses at all on Twitter: My Outlook emails were 'scrolling' 'jumping' all over the place! NO ANSWERS! I had to go into Chrome within which I had to 'log on' to so many sites..all requiring 'forgetten by me' passwords! Suddenly started working again on 5th April! Emails all there; right order, etc. If it hadn't been for these latest issues no-one got informed about, I'd have given more 'stars'! (thinking of changing from Firefox now)
Complete Failure
I been using firefox for a while now as my default browser. After a few months weird things started happening. Tabs started randomly crashing. My shortcuts would randomly change to recently visited stuff instead of what I had saved. If I were watching a video on one monitor, and browsing on the other, the video will sometimes pop in on the browsing monitor. You could say "GPU!" which is what I did, until I used chrome, and edge for a test and neither of them reproduced the issue.
As all tech companies do, first and foremost it's the consumer doing something wrong, not that there might be a bug or incompatibility with a new update. Then you go to the contact page, and low n behold it's nothing but "community experts" on a forum. Even feedback is handled by vote on a forum.
It's getting to the point where bailing on mozilla is probably the smartest thing to do.
I had been using firefox since its beginning
I had been using firefox since it transitioned from netscape browser in the 90's. I loved netscape & equally firefox. Surfing could not be better for many years. One year ago I noticed issues started to creep in. I realized that the support forum was either run by 'cut & paste' bots or by people that new less than I. Last year, for some unexplained reason, I could not reach my website. FF tagged extreme errors & kept protecting me from my own website. Frantically I went to their support forum & of course, no real help. I unchecked all protection from FF and same thing. I re-installed/deleted profile & still could not get to my website!
Then I installed 2 other browsers & 'Voila' my website with no issues. We are a members only website & I was the only firefox user :| All were telling me "who uses FF anymore ?
So bye bye FF - was nice while it lasted. Which browser do I recommend ? - any other than FF if you are having issues.

I use Firefox because of all the addons that work with it. There are continued updates on things I don't use or want but problems with Firefox never seem to be solved. Crashes after a recent update were bad enough but now I am having pages disappear. I am on a forum (like Quora ten minutes ago) and have typed a long answer, and before I can post it, it vanishes without trace. That is REALLY annoying.

cant access the support page in dark mode so have to fry your eyes trying to fix issues. So slow it crashes my pc and requires a reboot.
Not a fan anymore.

I find Firefox browser to be slow and resource-intensive, especially when compared to other browsers like Google Chrome. It often takes a long time to load pages and consumes a significant amount of system resources, which can be frustrating when working on a slower computer
use google to login
This new "use google to login" is absurdly stupid. why would you force this upon your users.

I'm using FF since many years. I use a few plugins.
The browser has teh feature I want but I'm constantly having problems with many websites. Spotify, kijiji, etc to name a few. One problems seems the cookies management.
Mozilla should focus more on the quality. New features is great but with an problematic broswer, it means very little.

What has happened to Firefox? So Slow!
What has happened to Firefox?. I used it to search and watch youtube. Now it seems to hang, with the thumbnails not opening, just blank squares. If I go to youtube using Google its fine. I'm looking for an alternative. It seems to have slowed right down the last few months.
Written by people who don't know what they're doing
Firefox is a classic example of people writing what they like rather than what users want and need. Hence we have a browser that performs like an absolute dog but has silly little features and gimmics that nobody needs.
The browser completely hogs memory to the point where it ruins your PC - I spent most of my career writing high-performance software, Firefox's claims that forcing extra usage of RAM is somehow "clever" and a good idea is completely misplaced... funnily enough, the guys who wrote Windows' core kernel memory mangement know a lot more about it than part-time open source developers, and memory management is best left to Windows to handle for you!
The latest update, far from improving the situation, simply hangs with "(Not Responding)" before I've even restored my tabs... the genius Firefox suggested solution is to close tabs (what tabs?!), close other programs, or even reboot your machine or buy more RAM!!! You do know we used to write programs that fit inside a few KB and you don't actually need to use 8GB to write proper software?!
I mean even the search box on the Firefox home page doesn't work, it jumps you up to the address bar... huh? What's the point of the search box then? Typical Firefox, all looks and no substance.
Sigh. Will have to switch back to Chrome, at least they know what they are doing!
With the latest update
With the latest update, they made every website work kind of like a text document, and this is extremely irritating.
This means that when you use the arrows or page up or page down keys to navigate, it will be from where the cursor happens to be instead of whatever your screen is currently showing, which makes for very confusing browsing.
Unless they fix this in the next update, I am sorry to say that I will have to say goodbye to this browser after more than fifteen years.
I won't rate this one star, since it is still better than the worst browser I have ever used, but it's also very far from the four or five stars I would usually put it at.

Was good but now crashes my system so had to dump it for good…very unreliable now
Gone from a nuisance to completely unusable
When I went back to Firefox some years ago it used to be ok most of the time, but every once in a while would crash and need to be restarted. Highly annoying, but since restoring the earlier session was easy it wasn't too bad.
Now, everything randomly shutting down happens on a nearly daily basis, and individual tabs crashing happens frequently. When clicking on a tab there's a 50/50 chance it won't have crashed, and some tabs crash time and time again each time they're refreshed. Other times, tabs randomly decide to refresh themselves when clicked on, as if the page had just been entered, leading to lost progress when trying to fill in something or do something. Every now and then a tab will even randomly turn into a blank page and the original page that was open can't be restored.
Other than that, it's also become very slow regardless of how many windows and/or tabs that are open, sometimes loading indefinitely. Add-ons for blocking ads frequently stop working so that they have to be turned off and on again. Several frequently visited webpages suddenly seem to think it's my first visit. All in all, using the browser has gone from annoying to unbelievably bad and completely unusable.
Falling behind the competition
Not only is it unreliable, with websites 'hanging' and frequent crashes, it is also now slower than its competitors. I recently switched to Opera. What an improvement – I wish I'd changed years ago.
A decent browser but very inconsistent
A decent browser but very inconsistent. Most of the time it takes up very little ram, but at times it just crashes, even though I've not opened that many tabs. I'm not sure what's causing it, tried getting it fixed to no avail.
Incredibly disappointing experience with Mozilla & Firefox account, don't care about GDPR either
Mozilla is one of largest organizations in the world being involved in technology and digital trust - see for instance the fact that Mozilla is one of the key root stores for digital certificates, which are a crucial component of a safer web (a job never done btw).
Mozilla's browser, Firefox, keeps evolving with ups and downs but has added very interesting features, such as the Firefox account which can be useful for sharing bookmarks and passwords across your devices.
I have been using different browsers, but Firefox, often provided by default on Linux, was one of my favorite ones, and the Firefox account seemed to work nicely.
This was true until 31 August, when I identified a more than likely trojan attack on my Windows computer, which appeared confirmed on VirusTotal.com as a serious one. That was all the more problematic that many commercial anti-virus didn't catch it and it appeared to mimic some system components.
One of the options in such case, if you don't have tools to stop the attack, is to reset your Windows system and keep your data.
Then, despite having my Firefox account password and 2FA app (as I took care to add a security step as soon as I set up my Firefox account), the connection process appeared to be changed, not asking me my 2FA but sending a code on a (potentially compromised) email account instead.
I contacted the Mozilla Firefox support asap, explaining the context of that likely security incident but :
- the support didn't react swiftly at all;
- no step whatsoever was taken to verify if I was the legitimate owner of the Firefox account
- the support ignored for six days or more my question about why the second verification step I set up was replaced by something else (my guess is that it was a conditional access policy, but Mozilla support should be able to manage that)
- Firefox support wasn't keen to stop sending codes to a potentially compromised email account, and those codes didn't work either ;
- as a kind of last resort, I then raised the issue to the compliance team, in charge, among other, of data protection and privacy matters. I took care to mention additional information to explain how critical this was for me. No response but, a number of days later, a meaningless message from the support that rephrased one of my questions but still, no help to understand what happened to my account;
- on my own, after 8 days, I managed to restore data from the Firefox account via Windows, something that is documented by Mozilla and that the support could or should have advised me to do asap.
- in that context, I then exercised my GDPR right of access with Mozilla compliance, to get access to the personal data linked to the usage of my Firefox account, to let me assess if there was any suspicious or illegitimate access to my account. Some kind of cut & paste generic message was received from Mozilla, but no personal data and no relevant information for this case at all - still the case as of today.
This gives me an incredibly disappointing experience, and it's still hard to believe that such an organization as Mozilla lets you down that way, especially after a potential or likely security incident, while a partial solution could at least have been provided by Mozilla support right on day one.
