Sound stops in the middle of watching videos on youtube, amazon prime, facebook, etc. Sometimes pausing the video, switching to another tab and switching back will solve the problem for a couple seconds, then the sound will cut out again. I've tried: clearing updating the browser, clearing cookies & cache, uninstalling extensions, reinstalling the entire freaking browser. It's driving me bonkers.

Running verson 121.0 on windows 10.

Suddenly my browser tabs moved to the top, above the address bar, instead of the bottom, below my bookmarks toolbar. I have tried the suggested solution using about:config then scrolling to browser.tabs.onTop. Unfortunately, browser.tabs.onTop does not appear anywhere in the list. What now?

Greetings, After installing WINDOWS 11, the Firefox browser in a search for obscene content on Google refuses to display results of obscene content and claims that the owner allegedly locked the option to unlock this. It is important to note that I am the owner of the computer, a 57-year-old adult, and the block only exists in the Firefox browser. I have already tried everything listed on the internet in attempts to find a solution to the phenomenon, including completely removing the browser and reinstalling it, nothing helps. I would appreciate assistance please.

I have a Trojan:HTML/Phish!pz - that is preventing my MS Backup completion.

...AppData\Local\Mozilla\Firefox\Profiles\76v4fpr5.default-release-1697121488518\cache2\entries\049E76616F10B0815855BCAA49ABC3C7EBA41C87049E76616F10B0815855BCAA49ABC3C7EBA41C87

File that has the Trojan : 049E76616F10B0815855BCAA49ABC3C7EBA41C87049E76616F10B0815855BCAA49ABC3C7EBA41C87

This file should not be in the Mozilla firefox file directories There is also no application that have added the trojan.

I can reach the login page for Duolingo.com using Chrome, but FireFox website always says I should advise the site Duplingo when I try to use Firefox. It still loads correctly in Chrome and I can use that. I've been using Duolingo in FF for years with no problem until today. I can't contact Duolingo in FF because of the same message. Suggestions please.

I cannot access https://www.tumblr.com or https://www.tumblr.com/dashboard, I just get a Server Not Found error. Other tumblr domains (such as specific blogs like [username].tumblr.com or their support database help.tumblr.com) all load fine, it's just specifically the main page/dashboard that won't load. Likewise, when I go to my own blog domain, the blog and all pages load just fine EXCEPT for the ask page, which displays the same error view in the ask box field with the rest of the page loading like normal (see attached screenshots).

I have done standard troubleshooting including clearing my cache (this did not work), reloading in troubleshooting mode to determine if the issue is being caused by one of my extensions (it does not appear to be), and refreshing firefox (also did not work). I can load tumblr just fine on both their mobile app and through firefox mobile, and I can load all other websites with no issues on my laptop, and I have confirmed with other firefox users that they are not experiencing the same issue. It's literally just 1) my laptop, 2) on firefox desktop version only and 3) this specific site. I've exceeded my own ability to troubleshoot this issue and would appreciate any advice on how to fix this.

My old computer crashed. I have the hard-drive in an external case and have it connected to my new computer. I installed firefox on my new computer, but I can't figure out how to get the passwords from the previous profile to my new profile. I have located the files on the old hard drive, but import will not work. Is there anything I can do?

I recently traveled to Australia for two weeks. While there, I used my mac laptop (with Firefox as my primary browser) on a mix of both wifi-without-VPN and hotel wifi with a VPN back to my home network activated.

I have been back home for more than a week. Other browsers on the same laptop as well as other devices (like my phone) that I took with me on the trip correctly reflect my location (east coast, USA). However, Firefox stubbornly insists that I am still in Australia. The net effect of this has been to break my access to YouTubeTV, which is not available in Australia.

I have tried: - Logging fully out of my google account on firefox and logging back in (at which point the 2FA prompt on my phone says I'm trying to log back in from Australia) - Deleting all cookies, cache and website data - Fully uninstalling Firefox, including deleting the Firefox folder in ApplicationSupport

None of these have had any effect.

Within YouTubeTV, I can force an update to my location, which will temporarily reflect correctly that I am in the US. But it still won't let me play anything if I'm using Firefox, and within Firefox, will soon revert to location unknown. Other browsers on this laptop, and other devices, work fine.

I am at my wit's end. Please advise.

I was in a meeting and needed to show my screen. Clicked the button at bottom to share and schecked entire screen then allow....it said firefox wouldn't allow me to share because of firefox. I also tried to just share Acrobat and had same result. What setting or plugin do I need to set to allow screen sharing in Google meet, microsoft team and zoom meetings?

Hi,

Firefox = 121.0.1 64-bit Win10 = 22H2 (19045.3930)

Not for the first time but the 3rd in the past few months I was closing a tab in Firefox and my PC immediately reset. No warning, just straight to blank screen as soon as I closed a tab (I had 4 open). Next thing I knew it was going through re-boot. No crash report in Firefox.

This last time I had Facebook open, I had a video in Facebook popped-out, it had finished playing and I went to close the FB tab.

Ian.

From [extensions, themes and hardware acceleration issues to solve common Firefox problems]:

> Note: If you have a large number of extensions, it may be quicker to enable more than one extension at a time. The method with the fewest number of restarts required is: Enable half the extensions in this list, then restart Firefox and test for the problem. If the problem reoccurs, you know that the faulty extension is one of the ones you just enabled. If the problem does not occur, you know the faulty extension is one of the disabled ones. Repeat the process until the faulty extension is found.

That's still slow. Is there a way to make this process quicker? In WordPress or Obsidian there is a plugin to handle this.

I am working on a website that uses Unicode extensively. Some glyphs do not show correctly. In particular U+2A75, which is double equals. I am using Ubuntu, and I have installed Unifont. In the image, I have opened Firefox on the right and Chromium on the left, the URL is https://www.compart.com/en/unicode/U+2A75 Chromium is displaying the page correctly, Firefox is not. However, in both cases, the character is correctly displayed in the text in the Tab header after the favicon. browser.display.use_document_fonts is set to 1 I have read the Support page on editing fonts. Inspecting the element as suggested in the 'Editing Fonts' page, (see 2nd image uploaded), I see - in the source pane on the left, the character is correctly displayed (as in the tab text) - the Font being used to display the character in the rendered HTML is 'Source Sans Pro', which probably does not have the glyph for U+2A75. - the Font supplied by the website (presumably it does have the glyph) is list as a font, but I can't find a way to have it display the element.

I have tried to change the font family for the selected element in the Rules pane, but that does not work.

I have tried a variety of other changes in about:config but nothing seems to work.

I have two thoughts - the Font family for some Unicode ranges may be set for security reasons, and so U+2A75 is forced to some other Font - the fallback mechanism is not working to select a font when the glyph is not in the first family.

I read this article on enabling/disabling hardware acceleration and I am missing the checkbox to toggle it. I am wondering if this is a firefox bug or if something about my hardware setup is unsupported. I'm using a 1080ti running on the most recent drivers, 546.33. Windows 10 Education version 22H2

If I search "lemmy", I want to see that in the URL instead of the full search URL: https://www.google.com/search?q=lemmy. It makes it easier to copy the search query. If the query has spaces than they're written with +s in the URL. I remember months ago this ended up being the default even for pre-existing Firefox profiles, but then it was changed back.

<Once I attached screenshots, this page erased everything I had typed previously... please fix>

I seem to have an infinite nesting of bookmarks. No matter how deep into "Other Bookmarks" I go, there is always a duplicate (not sure if identical or not) layer of bookmark folders.

Therefore, I cannot be sure where my webpage links are destined when I bookmark a new webpage.

How do I sort this out so that I only have "All Bookmarks" --> ("Bookmarks Menu" & "Other Bookmarks")?

In other words, I do NOT want "All Bookmarks" --> ("Bookmarks Menu" & ["Other Bookmarks" --> ("Bookmarks Menu" --> ("Other Bookmarks" --> "Bookmarks Menu... )) 'ad nauseum'

If this is my fault, please guide me on how to correct it. If it is a Firefox "undocumented feature," then please consider removing it in the future.

Windows 10 64bit pc. After factory reset and reinstall of Firefox, 2 extensions are enabled but the menu bar won't allow them. These worked OK before the reset.

Troubleshooting within Firefox won't work because it disables the extensions.

The messages from Extensions say "Can't read and change data on this site" The extensions are enabled (turned on).

The 2 extensions are Malwarebytes Browser Guard and Video DownloadHelper I am using DuckDuckGo as my browser. I tried switching to Google, but same problem.
