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.

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

Hello,

Since 2 step authentication has been added to the Mozilla add-on accounts, we no longer have access to this account. We have the email address and password, but cant enter the code for the 2 step authentication as the code is sent to an email that no longer exists. We have another account that we would like to transfer an extension to from the old email account. Is there any way to access the old account or transfer the extension from the old account to the new one without having the access to emails sent to the email address of the old account?

This is important to us as the id of the extension used within the non-existent account is preventing us from loading another extension with the same id. This is to prevent us from having to rebuild our NMH software that must use the appropriate id for communication.

Any help would be appreciated.

Some solid colours on certain webpages do not appear whilst on Firefox. The background will show up instead of the colour the image should be. I have tried to delete the cookies and cache on Firefox as well as trying Firefox in troubleshoot mode to no avail. Whilst writing this question, I have also discovered that taking a screenshot of the issue shows how the image should look as opposed to what the screen shows. Attached are some images of the issues I am facing, two images are of what appears on the screen and one image is the screenshot from the webpage which is what should have been shown. Apologies for some of the photos, I had to take a photo of the screen with my phone to show the issue. I have also closed the browser multiple times and restarted my computer, any help would be appreciated. Thanks in advance.

I've bought a new Win10 PC to (eventually) replace my old one.

I've signed up for a Mozilla account on the old PC, signed into it from the new PC and the favourites, history etc have come across ok onto the new one. The saved logons however haven't.

How can I get my saved logons to sync across from the old PC to the new one?

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.

I have incurred a browser hijacker that I can't seem to get rid of as no anti virus that I've tried will recognise it. The hijacker is defaultsearch.nchuser. The 'Refresh Firefox button is not working at the moment. Please help me to remove this pest. Thank you.

Windows 10 - Lenovo Thinkpad X1 Carbon This fall after an update attempt, Firefox started trying to update every time it was started. Deleted Update files in Program Data. FF would restart normally one time. Update data files were always replaced and the update on every startup continued - over and over and over. Tried refreshing FF- same thing. Uninstalled FF this AM and tried to reinstall when I get the following error:

XULRunner Error: Platform version "94.0.2" is not compatible with minVersion >= 94.0.1 maxVersion <= 94.0.1

No FF - HELP!

How can I change my primary email address? I'm not computer smart to find your secret language to do that. Please change my primary email address to: [email edited from public] @gmail.com Cable one has pulled the plug and disconnected my previous [email edited from public] @cableone.net address. No one can send any emails to that address anymore as nothing is there.

I hope you can please help me. Jan Kautz

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

Hi, Dear Support

Thank you for your browser, it's pleasure to work with mozilla firefox

Please, be informed, that link (https://developer.mozilla.org/ru/docs/Security/MixedContent/FixMixedContent) in page https://support.mozilla.org/1/firefox/87.0/Darwin/ru/mixed-content is not available.

Hi all,

I'm having a repeat of this issue: https://support.mozilla.org/en-US/questions/1291551

Again some links from emails have been giving me the "Warning: Potential Security Risk Ahead" page with the error message "SSL_ERROR_BAD_CERT_DOMAIN". I get this in safe mode but not in private browsing. I have tried all of the fixes suggested last time I asked about this problem including deleting cert9.db but that hasn't worked this time (so maybe it wasn't the fix last time either).

To be explicit, I've tried all fixes on these pages so please don't suggest them again without providing an explanation about why you think it will work (a technical explanation please): https://support.mozilla.org/en-US/kb/troubleshoot-SEC_ERROR_UNKNOWN_ISSUER https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can https://support.mozilla.org/en-US/kb/firefox-and-other-browsers-cant-load-websites https://support.mozilla.org/en-US/kb/secure-connection-failed-error-message https://support.mozilla.org/en-US/kb/connection-untrusted-error-message http://kb.mozillazine.org/Error_loading_websites https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean https://support.mozilla.org/en-US/kb/websites-dont-load-troubleshoot-and-fix-errors

My firefox menu all the sudden changed from the full drop down to only showing 4 options. Now I have to scroll quite a bit to see all the options. See attached picture. Anyone know how to fix this? This is very annoying...

Firefox continiues to wipe all of my saved password and bookmarks. After fresh windows install, I signed into my account and figured out that all of my bookmarks are gone. It happend for the second time. I have a mobile device running firefox which is lincked to my account. It's also gone there. How can I fix it or restore my data?

Hi, Happy New Year!

Finally I took a deep breath and hoping for no major surprises and bugs, I finally updated Firefox to the latest version.

I have a few questions:

1. As advised, every month I backed up info in the profile, following https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles Is there an up-to-date version of these instructions as the prior ones no longer work (menus were changed, Troubleshooting works differently, etc.).

2. Does the "Allow for session" option for cookies work and if so, what does it do?

3. Is there a way to change the way the TABs look now (washed out, white, very hard to see and differentiate, hard to see which one is the one I am looking at). I am wondering what is the perceived benefit of this change. In the old version I had, the tabs very clearly delineated and easy to see.

4. Where can I find a listing of the enhancements and major changes of the versions released since mid year 2021, from an end user perspective?

Thanks.

I moved my Firefox installation to a new machine. After creating a new profile and moving all my old files Firefox has opened with all of my old info and is operating properly.

But when I tried to change the location of the cache file to the correct drive on my new machine the about:config file does not save the new entry. When Firefox is closed and re-opened the new entry has been reset to the old location.

I've tried deleting the browser.cache.disk.parent_directory entry in about:config but when the program is re-opened the entry returns with the old directory shown.

Any advise would be appreciated.
