Firefox Support Forum

Almost every time I open FireFox, I get an error and have to click the "learn more" link. Once on that FireFox page, I can go other places. This has been happening all day long. Why?

Hi guys,

do I assume correctly, that if after-crash update to 89.0 wiped clean my sessionstore-backups folder, I've lost all my 50+ tabs forever? Firefox crashed, I started it and it opened with no tabs, like a new installation. I immediately went to sessionstore-backups folder and found that Firefox wiped it, created new empty recovery.jsonlz4 and recovery.baklz4 files and no other files are there (no, there are no alternative profiles in my Firefox directory).

I tried to recover deleted files using Disk Drill, however they seem to be corrupt, because the History Scrounger is not able to decode them. Does anyone have any other ideas, or is this it and I just have to move on? It was on my work laptop, so recovering the tabs would be extremely helpful and would save me lots of time and possibly some trouble too.

Thank you, Sam

Hi, hoping someone can help point me in the right direction....I have a web app that has lots of data, we run several scripts that can take a while to process. All was operating fine on version FF87, version 88 would just stop processing the script and the browser would not allow me to do anything else on that site. ... there were no error messages (that I can find).

I downloaded the Beta of V89 and all worked fine Public release of V89 has the error It works fine on all other browsers It works fine on the local server version on my machine

site is php7.2 ...

...any information would be helpful to me.. please and thank you in advance!!

Firefox updated to version 89 last night and since then I cannot properly view certain websites I use regularly such as BBC news and Vimeo (have uploaded pic to show). I have restarted computer, and turned off hardware acceleration and cleared cache and cookies - these don't help. If I start in safe mode it's all fine - I've disabled any extensions and themes and tried again but the problem is still there. All was fine before the update. Not sure what to do next.

I have recently had an issue in which I went over to Amazon, only to have firefox claim that there was an attempt at a cross site scripting ("XSS") attack. I normally just set these to be blocked, as I usually find it better to err on the side of caution when I see that popup. However, this appears to be a false positive, as now I cannot use Amazon's 'look inside' feature when I use the site. As this supposed XSS warning was the only thing that recently cropped up, I have to assume that this is why this piece of Amazon's website isn't functioning properly. How do I check on what I have blocked and how do I unblock anything that has since been discovered to be a false positive?

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

I installed the Waterfox browser and did the addressing method for Japanese localization. However, Japanese does not appear in the pull-down.

The General page is displayed. Scroll down the page to the Language item, click the English (United States) pull-down, and click Japanese to select it.

I want to translate it into Japanese. Please help everyone.

Hi, volunteers!

About an every every hour or two, Firefox shows a compelled "Restart required" page with a "Firefox has just been updated in the background" message, which yet absolutely sure has nothing to do with disabled automatic updates.

These and pyllyukko's user.js preferences have been set:

• browser.cache.disk.enable;false
• browser.cache.disk_cache_ssl;false
• browser.cache.memory.capacity;5000000 # -1
• browser.cache.memory.enable;true

The page is shown either hard or solid state drive is used with 8 GB RAM on board, `free -h` shows more than enough. "Storage disk location" value for `memory` and `disk` (except `appcache`) from the `about:cache` page is "none, only stored in memory".

Appreciate your time and efforts, this message haunts me no matter what for so long.

Suddenly! Cannot open Firefox because of the error message: "Firefox profile missing or unavailable."

I found the profile in my Library.

Looked for internet advertised "Firefox profile manager," but could not find it. Only one I could find was obsolete.

Thank you.

Hello,

Firefox crashes on startup since version 89. The crash doesn't happen in Troubleshoot Mode.

I have tried everything following "The problem does not occur in Troubleshoot Mode" on this page, but it does not help. https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems#w_the-problem-does-not-occur-in-troubleshoot-mode

Thank you.

I have an older PC but it was working fine with Netflix and Prime Video until this latest update (v89.0). It seems that when I try to go to Netflix or Amazon Prime Video the browser crashes almost instantly, and usually shuts my whole computer off. It doesn't go to a blue screen, the computer just decides it's time to reboot. Now again, I'm using an older machine (and I can't afford a new one), but this was never a problem until this latest version of Firefox.

I am also not a fan of the aesthetics in this version and I'm wondering if I can revert back to an older version where the crashing was less frequent. Any help would be appreciated.

Hey!

I'm new to Firefox and I gotta say: it is the prettiest browser out there!

But there are some things that are trully bothering me and would like to know if it is normal. I would like love to keep using Firefox because of its beauty, but with those things I don't think I'll be able to.

Here are the things: * Performance on Firefox is bad if compared to Opera GX or Edge. Yes, I did enable the hardware acceleration but still... scrolling down on Facebook is choppy (don't know if it is an appropriate word, but still), opening and trying to move the screen on Roll20 (virtual tabletop) and some more... Any clues?

* Websites are not the same Sometimes I see a website with different styles that I was used to see on Opera GX and Edge. Trello scrollbars is an example of that. On Opera GX and Edge, it looks thin, clean and modern, while on Firefox looks like that old, fat scrollbar. There's also a system that I use that all buttons are on the right side of the screen but on Firefox they are on the left side, some inputs starts from the far-right to left intead of the regular left to right and so on...

Could you guys help-me with that? Is everything working as they supposed to?? This new version of Firefox looks amazing but these things are making me not use it.

Here are some details of my computer in case anyone wonders when reading the first topic:

• i7 9750H
• 1660TI 6GB
• 16GB of RAM
• 500GB M.2 NVMe SSD Samsung EVO 960

Thanks!

Hi,

I'm developping a custom tool in order to automatically clean my cookies from several websites. For example, I would like to automatically remove cookies from twitter.com every time I launch my tool. I'm under Win10x64, firefox v89, tool developped in python.

To do this, once firefox is closed, my tool go in my profile folder, access to cookies.sqlite and delete row associated to twitter.com

-> DELETE from moz_cookies WHERE host == '.twitter.com';

The database is saved, no more "twitter" in my cookies.sqlite file, and the tool ensures there is no cookies.sqlite-wal or cookies.sqlite-shm files left.

After that, when I open again twitter, I am no longer connected to my session, but I got an error which seems to be related to cookies (see screenshot).

Moreover, when I oppenup the firefox cookies manager, there is still twitter cookies in the list, but 0 cookies associated.

Where is my mistake ? Can you help me solve my problem ? Thanks
