When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?

Almost every time that I open a new session of Firefox I get a message that there is a problem and it needs a refresh, which removes the extension I use all the time. Any ideas why this keeps happening over and over and what I might to resolve the problem?

When I pause a video (any site) and go to another tab / stay on the site, after a seemingly random amount of time the video starts playing again.

I'm using latest Firefox on Ubuntu 22.04 (snap).

I've tried (didn't work):

• Disabling media hardware controls through about:config
• Disabling autoplay through about:config

I realized since I upgraded my MacMini to 14.4.1 I can no longer 'post' into any of the yard sale/garage sale sites I am on, not even MarketPlace. All I get after a long wait is a 'technical problem' notice. Am I doing something wrong?

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

the built in eyedropper tool is the simplest and easiest solution to grabbing screen colors without granting file permission to 3rd party solutions for full funcionality. I have power-toys but I hate to see this tool needlessly depreciated. My workflow needs to sample many colors at a time making the menu navigation needless. PLEASE let there be a way to add it to the toolbar, I hope there is. Thanks for your time

I'd like to be able to open a link in private mode by holding down some modifier key, then clicking on the link. There are many times that I want to open a link in private mode, and a keypress + click would be the quickest way to do it given that one hand typically remains at the keyboard while I use the mouse/trackpad.

I've even added a toolbar button to open a new private browsing window, then dragged and dropped a link onto the button, but that gets a circle with slash icon and nothing more.

Others have asked this question, so, to be clear, none of the following address my question: copying the link then opening the private browsing window & pasting the link, using a customized shortcut/bookmark, opening Firefox in private mode via command line, right-clicking the link then selecting "Open link in new private window".

Thanks for any advice and thank you, Mozilla, for Firefox!

Currently unable to save, edit or add bookmarks.

I have updated Firefox, refreshed Firefox, gone through Troubleshoot mode, cleared the startup cache, and deleted the "xulstore.json" in my profile folder.

Pls help this is driving me nuts + making me want to switch browsers. Thanks : )

Hi everyone!

Jack here. I am a non-tech person and don't know the technicalities behind this issue. I have a Digital Media Website which loads and works quite fine when opened in other browsers but the site is loading very slowly in Mozilla and when it does load it has breakages.

Can anyone please tell me what the issue might be and how to fix it?

Thanks, Jack

I heard that the newest version of Firefox (which I have not upgraded to yet) has a feature that makes it easier to accidentally visit a website whose URL is on the clipboard. I googled to find out how to disable it, and the Featured Snippet said "go to about:config and change clipboard.autocopy to false." Sounded simple, so I did it, but subsequently found out that the article it quotes from is 10 years of age!

My first question, then, is: what does changing "clipboard.autocopy" to false do if it doesn't turn off the brand-new feature?

The second question is, how do I disable the new URL Paste Suggestion feature? Will setting "clipboard.autocopy" disable it? In particular, I want to make sure that the browser does not pre-load or pre-fetch the clipboard URL, and in fact, I wish to pop up a dialog box any time I do "paste and go." People often copy URLs from e-mails to research them before visiting them directly; jumping directly will increase the likelihood of visiting an imposter site.

when open games not loading until close " enhanced tracking protection" switch

and next time even it is close not open until make " enhanced tracking protection" switch open and reload page and then closed and reload page again to open and every time like that

Firefox is not opening. Every time I try to use it, I get the message:

" We're sorry. Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts."

I have submitted the crash report: Crash ID: bp-51f17766-7a20-41dc-ae3d-27ab10240501

I am running it on Fedora 40.

Thank you!
