I accidentally uninstalled the wrong version of Firefox on Windows 10. I uninstalled the Firefox Version I was using. Therefore, I need to get back my current version with my bookmarks. Is this possible? Does Mozilla Firefox keep these on a server somewhere I can download it from?

Recently, Chase seems to have disabled autocomplete on their login pages (www.chase.com and secure.chase.com). Saved usernames and passwords no longer auto-populate. Yet, Chrome and Edge have been unaffected. Can anyone at Mozilla address this?

My blog has started displaying the message, "Firefox can't open this page". The message also says, "To protect your security, accounts.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window." But opening it in a new window didn't work. I tried clearing the cache, and pasting the link into a new open tab, but neither helps. I tried opening it in Safari, and that works fine, so this seems to be a Firefox problem. Any suggestion?

I am debugging a Web page that performs several AJAX requests.

To this effect I sometimes find it convenient to reissue an AJAX request (from the Network pane of Development Tools, right click + "Resend") and would find it even more convenient to open the request in a separated tab, as was possible until, if I recall correctly, four or five months ago.

Now the latter option does not work, likely because of some security tightening - the "new request" might be seen as a different context, I don't know. The AJAX endpoint receives no cookies, so it can't load the appropriate state, and restarts as a blank slate with a new cookie, which makes the reply useless to me. Even worse, at this point the new cookie value is propagated to the originating window, effectively crashing the entire debugging session.

Is there some way of disabling this option and reverting it to the older, less secure behaviour, on my own development Firefox only?

When trying to listen to music on Spotify I get this error: "The WidevineCdm plugin has crashed". I followed all the help section suggestions both on Spotify and Firefox, and nothing worked. I get the error message in Incognito mode, too. I did a fresh reinstall of FF and disabled all extensions. I also verified that WideVine was activated. Spotify works in Edge, so I know this is a FF issue.

Up to 126.0b9, files with encoded URLs in their filenames downloaded normally. As of 127 onward, however, it gets changed to _3A instead of %3A, etc. Is there a setting somewhere in config to revert this?

Example:

Supposed to be: test [sound=https%3A%2F%2Ffiles.catbox.moe%2Fe547nk.mp3].png Downloads as: test [sound=https_3A_2F_2Ffiles.catbox.moe_2Fe547nk.mp3].png

I have been unable to open linkedin.com for a while. Outside of troubleshoot mode, the browser just hangs at the loading indicator. In troubleshoot mode, the browser crashes. I have crash ID bp-c4155ea6-2f98-41dd-bbea-9ac240240920 as my most recent attempt. Does anyone have a clue what could be causing this?

Every time I try to login, the progress resets. I enter the password enter the verification code and it brings me back to entering my password. The cycle repeats again. Before this, the account would log out automatically while syncing.

MacOS 14.6.1 Firefox 31.0.3 (aarch64)

I have a long (19000px) table with a sticky row at the top. On Safari or Chrome it works fine. On Firefox it works for around 800 px and then becomes 'unsticky'.

Is this a known behaviour?

I updated my Malwarebytes protection 3 days ago and since then I cannot access my Windows 10 programs using my Firefox browser as before ! I heard from Malwarebytes there could be some incompatibility between Firefox and their latest update but they had no information as yet .. Is Firefox working on this problem and when will it be fixed? I do not want to use another browser..

  Many thanks in advance.   Peter B
