Firefox Support Forum

Hi...

Is there a way to edit bookmarks sidebar right-click menu. I want to change position of "Delete folder" and "Delete bookmark" to bottom of right-click menu.

Thank you

Since Firefox 11 installed onto my PC, I get about 15 instances of Firefox running in Task Manager, and uploads onto a podcast website are impossibly slow so that I am timed out from podcast website. Short video upload onto FB takes an hour now via Firefox11. The "Performance" fix has no 1-8 option anymore, unchecking "Use recommended settings" does nothing. Any solutions to suggest?

Processor 11th Gen Intel(R) Core(TM) i7-11700 @ 2.50GHz 2.50 GHz Installed RAM 32.0 GB (31.7 GB usable) System type 64-bit operating system, x64-based processor Edition Windows 11 Version 21H2 OS build 22000.613

Whenever I try to update to a new version of Firefox from v86.0.1, they frequently crash out while trying to use a Save or Save As command. I have tried with multiple versions up to this v100, and they still do it. I have always had to revert back to the v86. I have tried most fixes that are shown on your help site, and in the Firefox settings. I am using the following hardware:

Processor AMD A10-7700K Radeon R7, 10 Compute Cores 4C+6G, 3400 Mhz, 2 Core(s), 4 Logical Processor(s)

AMD R70-370 Direct X 11 12-gigs of RAM 2-gigs of Graphics Card RAM Windows 8.1 version

Thank you very much for your help.

Hello,

i just downloaded the "Firefox Setup 100.0.2.exe" from https://download-origin.cdn.mozilla.net/pub/firefox/releases/100.0.2/win64-EME-free/de/ and the checksum is different to that offered in https://download-origin.cdn.mozilla.net/pub/firefox/releases/100.0.2/SHA256SUMS or SHA512SUMS. Who may fix this or am i wrong at least?

Regards, Martin

I have a php file with an html video tag which recently stopped working in Firefox Developer Edition (FDE). It still works in other browsers. In FDE, the volume is permanently muted. I can't find a way to turn mute off. In About:Config under Media: there are messages at

media.decoder-doctor.new-issue-endpoint = https://webcompat.com/issues/new

and

media.decoder-doctor.notifications-allowed = MediaWMFNeeded,MediaWidevineNoWMF,MediaCannotInitializePulseAudio,MediaCannotPlayNoDecoders,MediaUnsupportedLibavcodec,MediaPlatformDecoderNotFound

The partial source code is:

2 laptops were syned to your browser , this one is windows 8 and uses a ethernet cable the other one is on wifi and windows 11 which all of a sudden is not responding to load the websites although after running on it prefectly until this morning, the windows troubleshooter shows the wifi signal is connected and fine, please check and advise.

So I am working on my own website & a couple days ago I got a requested headers too large error. After looking up what that meant, I cleared my cookies & cache but it didn't work. After looking it up more I renamed (added .old) the coolie file in my profile & I thought maybe it worked for a while but then all of a sudden it came back. Now I keep getting the requested headers too large error like every 5 minutes & have to keep clearing cookies & cache every time, which works for 5-15 minutes & then it happens again. Which is more than extremely frustrating when I'm trying to work on my website! And it's only happening on my site.

So how can I fix this for good? Is the cookie file getting corrupted again? If so, how to I prevent that?

I did not do anything and opening firer fox to get to my mail at inbox in outlook. I also use the calendar provided. Simply I can't get to my calendar it reads an err and try again later. Can you tell me how to get that back as I have a lot of data recorded on it? Thank you.

This happens in Facebook when I try to play a game: "The address wasn’t understood Firefox doesn’t know how to open this address, because one of the following protocols (fb-messenger) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address."

When I create a tab by clicking on a link, normally the tab will open to that link after a small delay. But some tabs just sit there, seemingly dead to the world. I've tried refreshing by hitting enter, or when possible (which it usually isn't) the refresh button on the taskbar, but nothing happens.

If I create a new tab, and cut and paste the link from the old one to the new one, usually the new one will open right away (after the usual delay). Meanwhile, the old one just sits there.

This has happened before (in much earlier versions of Firefox) in a small percentage of cases, but it is now happening with some frequency. I am currently using version 78.0.1 (64-bit).

Firefox usually works great, but starting last night it has been messing with my computer like crazy.

I have a wireless mouse, and a Wacom tablet/pen. Everything has worked fine, but starting last night I had to Restore Down the Firefox window with the Wacom because nothing happens when I try with my mouse. Once the window is has been Restored Down, my mouse freezes, and I have to go into Task Manager with the keyboard to get it to work again. I then have to use my Wacom as a mouse if I want to click something in the taskbar, the mouse for the start menu and any non-Firefox programs, and Firefox will just not work at all. I can't switch/open new tabs, I can't click the address bar, or the search bar, I can't go to a different site, or anything.

I have to open Task Manager to close out Firefox, then everything works fine. I reopen Firefox and it works fine except not being able to use the Minimize, Rrestore down, and Close buttons without using my Wacom, and then when I do, the cycle repeats.

I have tried unplugging things, putting in new batteries, nothing has worked and I don't know what could be causing this issue when Firefox has worked great for me all these years. I'm currently running a virus scan on my PC, but I don't see why it would ONLY be effecting Firefox.

For the past week, on every start up, Firefox requests to do an update. I agree, but if I shut down and then restart later, it asks the same question. On and on for some 8 days now!!!!! How do I stop this?

Firefox now forces PDFs, even downloaded ones, to be opened in-browser. Frustrating is this setting has been introduced and right away replaced previous behaviour without any preceding notice, perfectly fine settings, now requiring to go to file explorer to open a PDF as if it was a file. How to disable this bloat?

I used to have an extension. But after removing it I still see its setting in about:config. I don't want to clutter my Firefox's profile. Look at the screenshot.

1. Is it safe to remove all these setting manually? 2. How can I confirm that all the unnecessary data is removed? (including sqlite databases, etc...) 3. Isn't it a responsibility of an extension's developer to remove all the settings when a user removes it? 4. If I install hundreds of extensions and then I remove them, will they remain in my profile after deleting?

Hello

I downloaded the newest update and now pages are loading with only text or barely anything at all. Some sites work and others don't. I know this problem happened in previous versions and there was a fix for it. Do you know how to fix this problem? Thanks.

I have added a picture of how the pages are loading improperly with just text.
