So, for about a month or so now I have been experiencing random freezing in Firefox on my home PC running Windows 7 (I know it's outdated, it's by choice). I'm pretty certain it started after a specific update, but at this point can't tell which one.

Here's the behavior itself:

Firefox completely freezes and soon after the window turns white and a 'Firefox stopped responding' dialog pops up. After I close Firefox, I am able to restart it normally. However, at restart, it says 'Oops, there was a problem restoring your session' but then successfully restores the session if I click the button or select the option from the History menu (however, this does not always pop up - see the 'what I tried section').

When it happens:

1) When interacting with input forms such as login and password forms. Seemingly happens more often with forms that have previous input saved for them, but I'm not sure.

2) When opening new windows (notably NOT new tabs) such as when opening a private browsing window, bookmarks window, download history window or when using the picture-in-picture option on Youtube.

How frequently it happens:

The frequency appears to be random and not specific to any website. It most often seems to hapen after about an hour of browsing, but can also happen immediately at restart or go longer without freezing. Interestingly, disabling Ublock Origins seems to dramatically decrease the frequency of freezing, but does not eliminate it completely.

What I've tried so far:

1) Looking for problematic extensions. Running in safe mode seems to prevent the issue, so I started disabling extensions one by one. Ultimately though, even with all extensions disabled outside of safe mode, the issue persists. As noted above, it seems to freeze less often when Ublock Origins is disabled.

2) Tracking memory and CPU usage. Nothing abnormal there - I have 16 GB of memory and Firefox rarely goes over 5.

3) Refreshing Firefox. This did nothing except cause the 'Oops, there was a problem restoring your session' tab to first start appearing. Before the refresh that didn't used to happen at restart.

4) Disabling hardware acceleration. No effect.

5) Removing bookmarks. I had a very large number of bookmarks saved so I deleted a bunch of them. No effect.

6) Deleting the places database. No effect.

7) Deleting the session restore files. This has been the most interesting option. Deleting the session restore files DID stop the freezing... until it came back again in a couple of days. Interestingly, when it first came back it was not accompanied by the 'Oops, there was a problem restoring your session' message at first, but eventually that started appearing too. This gave me the thought today that perhaps this is caused by a website somehow 'corruping' the session data. I was going to delete the session restore files again and start looking for the offending website, but puzzlingly, this time deleting the files did not stop the freezing.

I have used sync for long on several devices and different operating systems (Win 7, Win 10, IOS) in parallel. Most interesting and useful is for me synchronisation of the toolbars with Bookmarks. It worked fine up to today. Today I opened Firefox and found my bookmarks as they were about two years ago. Oops... so I tried to synchronize but failed. No changes were applied to my bookmarks. I assume, my bookmarks are also being stored on several other devices I used for Firefox. However the newest sinchronization on the mozilla server does not contain the accurate valuable data. How can I manage to save sync data from a destinct device to the sync server and determine that as the current data set to be valid for synchronization with all my other devices? In other words: set the direction for synchronization. I did not find this option on my current (82.0.3 (64-Bit)) installation. Could anybody help me? Thanks Juergen

Facebook sub positively sent me an email with a verifying account code that I did not receive. Problem: I cannot sign in to Facebook. I receive other emails. Could there be something in my fire fox settings. I use Win 7.

Hello, after an update the css is presented incorrectly. I tried on other devices, still the same. In chrome is working fine. I did not make any changes in the code. It was working and after the update i am facing css problems related with (display: flex) and (display:inline-table). Will it be fixed with an update?

I have uploaded two images (the correct and the problem)

When you are presented with a text field, sometimes when you type, a small list of words you entered previously will drop down. You can then select one of those previous words, or continue with what you were originally typing. This is the Autofill feature for Firefox.

Lately, it has been a pain. After an hour or so of use, the instant I click on a text field to type something (usually for searching), the autofill box would partially drop down, only for Firefox to completely hang up. Once you recover from the initial crash, the autofill bug would not appear until at least an hour later. I tried turning off Autofill, but it cost me access to my History, so I was forced to do a complete browser reset. This issue has been with me for about a couple of weeks, and I have no idea why it's doing this.

Hallo, i have the following problem. If i try to use Whattsappweb i always get the report yuor firefox is not the newest version. whenm i go in the feirefox menue, i get the report firefox is the newest version. What to do now?

(I have bad English, sorry.) Hello! May I ask? Is it possible to officially download older versions of the FireFox browser? And at the same time that they work and open sites. Just, I have an old netbook, in general, all new browsers do not work well. Thank you in advance for your answer!

I want to install Firefox on a new Windows 10 PC which has an SSD for its C: drive and an HDD for its D: storage drive. I would like to minimize SSD usage if possible and know that the FF profile can be moved to the D: drive.

I did quite a bit of searching & some people have a lot of SSD activity & say to move a cache folder or the AppData/Roaming folder. Other people don't seem to have a problem.

Is there a recommended configuration in order to minimize SSD wear?

Thanks.

I would like to use the amazon.com (and wikipedia.com) search engine and keyword. But since I have installed a non-English version of Firefox (or maybe because the default language of my OS is non-English), I get defaulted to amazon for a different country (and the Wikipedia for that language).

How do I get the US / international version as default?

When I add a bookmark Firefox puts it in either "Other Bookmarks" or "Bookmarks Menu". Having to hunt in two places for new bookmarks is infuriating. How do I get the programmers to add an option in about:config to remove or disable "Other Bookmarks" so that new bookmarks are just added to "Bookmarks Menu" like they should in a normal world?

Typing the problem in the quote marks in the search box yields over 400 identical questions. So obviously this is a known problem with FF, and hopefully with Mozilla.

With me it happens on Facebook. Clicking "wait" basically does nothing, clicking "stop it" it basically stops the page from loading, so you can't post a message or have any interaction with the site whatsoever.

All along I'm watching the CPU at a constant 50%-60%, and memory for one tab of FB going up steadily from 400 MB to 1.2 GB (almost like a memory leak).

Now, my laptop has really limited specs, 3 GB RAM, Win 7, 10 years old. So I thought the laptop is probably to blame. Till I did the following experiment: Let's try Edge, with the exact same tabs, exact same sites.

So, one tab of the same FB page + one tab of Yahoo Mail -> FF: 60% of CPU, 1.5 GB of memory (and counting). Edge: 10%-15% of CPU, 500-600 MB of memory, and FB smooth as silk.

Any suggestions/solutions are welcome.

Hi All,

I am using a Desktop Windows computer and I am having trouble with 64 bit Firefox Version 87.0. For some reason I cannot play the sound in Instagram videos. All instagram videos will play but wil show the sound icon as muted and there is no way to click the sound icon which is shown in the lower right corner of the video to unmute it.

I disabled all the add-ons in firefox and I still am getting this problem. Chrome on the other hand seems to work just fine in playing Instagram videos with audio.

So what's up with Firefox?

Dear Volunteer. Not "yelling" at you personally, but...

PLEASE discontinue “A web page is slowing down your browser.” It’s useless, and EVERYBODY hates it.

Since this "improvement" was force-fed to us, the opening of almost every site gets hijacked and frozen by a redundant alert.

Please at least give us the option to disable it. Seriously, I see (Not Responding) in the activity windows more than anything else since the idiotic yellow bar made it's unwelcome appearance.

PLEASE kill it. PLEASE, PLEASE, PLEASE, Thanks.

Hi, Using the updated Firefox on Windows. The Delta home page works but when I do a search, the results don't load. "We're sorry there was a problem processing this request. Please try again" This has been going on for about a week. I set cookies to be allowed from Delta and there is no difference. Please let me know your suggestions. Thanks, Michelle R
