This issue has plagued me ever since I switched for Firefox. I have NEVER encountered this issue with any other browser. Once every week or two I will encounter a page with an MP3/MP4 file and will be presented with this error. I have already tried clearing cache, disabling addons, reloading, etc, but I guarantee the "best answer" will just be some rehashing of these steps. Something is fundamentally broken with this browser, and there are hundreds of people across various sites reporting it. Fix it.

Hi,

Whenever I make a bookmark, it automatically puts it in the Bookmark Toolbar, but I want it to default to the Bookmark Menu. I can't find any way to do that and can't find any good information about it. One site said I needed an ad-on, but I shouldn't need that for something so simple that used to work fine on my old computer with Firefox. I can't find any settings for this at all.

Please help me fix this.

Thank you,

Myrah

Last Pass not working properly in Firefox

I downloaded Last Pass through Firefox years ago...almost as soon as became available. The prompt for the Master Password does not function as it should but it does on Microsoft Edge. I've spoken with Last Pass on this and we added it to Edge in order to test the results. The result was that the Lass Pass icon on Edge remained lit but was not lit on Firefox. It should re-time itself whenever Last Pass is utilized and I use it for all my log-ins throughout the day...every day! I do not like Edge and use Firefox exclusively. I find this situation extremely disconcerting. I've been asked to enter that Master Password again and again within the 24 hour re-prompt schedule...at times within minutes! This should not occur. Please fix this glitch. It's between you or your developer and Lass Pass. It has nothing to do with me

I just upgraded from 88.1.0 to 114.0.2, and regret it. How do I reduce the wasted space? The search bar, menu bar, etc. And how do I get rid of the double spacing in my bookmarks & history? So much wasted space.

I'm currently working on building a website, and while testing several of the front end parameters I'm just hitting a wall with firefox incognito's ability to clear the cache.

After I clear the cache, it's obvious that it's worked on the regular browser, but no matter how many times I clear it, how long I wait (this has been a 2 day ordeal), or how much of the history, cookies, cache, etc that I clear, the private browser information will not clear. Closing all windows, restarting the computer doesn't work.

I've changed aspects to a form and other aspects to a particular page, and am in the middle of doing a conflict test so every one of my plugins are off so the site looks 100% different on the main browser, but the private browser is stuck in the past.

Thoughts?

First, after the newest version of the desktop browser auto loaded, the colors theme I had been using was gone. It is saved, but I can't seem to get it established as the default theme.

More important—and I'm furious about this—I kept getting message about hidden tabs. It was quite annoying. I clicked on "delete extension" because I wanted to stop getting these messages. Instead, it deactivated my Speed Dial extension, and I can't figure out how to reactivate it. This extension is essential to just about everything I do on the web. It would take me days to reconstruct, and even then I doubt I could complete recreate it.

Please tell me how I can reactivate the Speed Dial extension. It is still listed among my extension, but it is listed as deactivated.

Dear Mozilla Team,

I have severe difficulties with my Windows computer to open many websites I want to open, even those of banks I normally can easily enter.

Do you have any advice for me how to fix that? I searched in the help function but found the advice to be insufficient. And I also found no way to manually change the setting for the individual pages.

Thank you very much for your help.
