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.

See reddit post— no way I'm typing all that again! Reddit Post It's not that long, trust me— it's just that the code is long... I've attached a slightly different screenshot to the one I posted on the reddit post, but it makes no difference if you see one or the other, or both!

In summary, I've added a css code to my userChrome.css thingy to move the tabs below the search bar. I was also wondering what the best way to transfer my userChrome.css file + about:config settings over to a new version of Firefox. Due to not being admin of my laptop (I'm running it out of the .dmg file— besides, I always like to keep an older version of Firefox as a fallback), I have to install a whole new version of Firefox onto my laptop to update.

Thanks!

Before the latest update, I was able to open links (eg zoommtg:) but that quit working. I originally thought it was a problem with Ubuntu, but I tried in Chromium and it seemed to work fine. In addition to not being able to open links, I can't click on the "Show Folder" in the downloads dialog. This leads me to believe Firefox is having trouble communicating with the desktop.

  • OS Ubuntu 22.04.2 LTS
  • Firefox Version 114.0.1 (Snap)

Ideally, I'd like to find a log or some indicator as to why this is happening. It's quite annoying because I find myself doing a lot of copying and pasting of links and what not. Any help would be appreciated.

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

Hey, hope you're well

I'd prefer opening new tabs to happen in the background, so I can stay on the original page.

So far, Firefox seems to open new links and will switch to them immediately, automatically.

I checked in settings, and found the setting in the attached image.

I found that whether this setting was checked or unchecked, the behavior remained the same.

Any suggestions?

Thanks in advance

Hello,

On some websites Firefox is displaying strange text/characters. I've tried refreshing and troubleshooting, I've uninstalled and reinstalled, and the problem was fixed for about 24 hours, and now it's back. I have confirmed my language is sent to English.

Has anyone experienced this? And if so, how did you fix it?

I don't want to use another browser, but at this point it looks like I'm going to have to. Everything displays properly on Chrome.

Why is it Firefox can't control META timelines. Both Facebook and Instagram jump down several posts while scrolling.... I was going to blame it on META till I found this doesn't occur with Chrome or Edge. Firefox is my preferred browser due to the many addon's available.

I started Firefox and apparently it was being updated. When I finally got into the browser, it was totally vanilla. All the old information, bookmarks, toolbar information, were missing.

I frequently use the website Cookie Clicker. After Firefox updated, all the history/cookies for Cookie Clicker seems to have been deleted. I think that only the Cookie Clicker website has been affected... which sucks because I made a LOT of progress in that game. Is there a way to fix this, or am I out of luck?

The Pizza Hut Rewards site won't complete login. It just has a o with \ through it. After a while, the reCAPTCHA will say that it timed out and need to check box again. I do that but, it still doesn't complete.

I called Pizza Hut Rewards and they told me to use Google Chrome (which I don't trust).

I have tried this in both regular and Private Browsing mode with same results.
