I had an issue with the hidden task bar not showing up when I moved my cuser to the bottom of the screen, so I was "playing around" and messed it up. I created another profile, but lost all my bookmarks and so forth. I copied files from my old profile to the new profile, but now I can't get to michaels.com - it won't load. Also, I have my yahoo mail tab looks like it's loading, but I got in my email and when I went to blackforrest.com it does the same thing.

I still have the issue of my task bar not "unhidding" when I go to the bottom of the screen. I have to minimize my screens to see the task bar.

Can you help, please?

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

Whenever I close Firefox and try to reopen it, it brings up a system error that says, "The code execution cannot proceed because C:\WINDOWS\system32\pmls64.dll was not found. Reinstalling the program may fix this problem." I've tried completely deleting Firefox and reinstalling and it opens a new tab, but when I close it i get the same error message.

Decades ago, browsers had features to download the current web page along with linked pages and store them locally including updating the downloaded main page's links to reference the linked copies. It was even possible to specify how many link levels to copy along with the main page.

when web page sidebars became popular this became problematic for a while since sidebars often linked to ads or unrelated content (Wikipedia or GitHub for example). Then browsers started providing a means to disable webpage sidebars and display only the main page.

I can't find any of that capability in Firefox. I have searched the settings, extensions, Firefox support pages and found almost nothing related to simply saving web pages.

I fear that some day the website 'UESPWiiki' which provides support for my favorite game which is now (2025) 19 years old will some day go away. UESPWiki has side bars preventing simply downloading everything. Help.

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

I can't reproduce it, but sometimes the URL bar becomes unresponsive. You click on it and nothing appens. I've tried to delete cache and history, but nothing changes.

Hello all, I have the same exact problem described in post https://support.mozilla.org/en-US/questions/1463436, dated 9 December 2024. Until ten days ago (more or less) all was working correctly. At the beginning I thought there was a problem with Intesa because Intesa had problems in all the country in that period, but I have now tried CHROME and found that is working correctly. My system uses Firefox 139.0.1, W10-32 and Iliad FTTH. I have already cleaned cache and data from settings but the problem remains. Any thought? Thanks very much for any help. Mario.
