Firefox Support Forum

Hello,

I have more than 30 extensions, but I cannot add an extension shortcut into my toolbar and no extension appears in the “Customize Firefox” view. I tried “Restore defaults” without any effects...

There is a way to fix this issue or run Firefox in verbose mode to more information why my extensions don't appear here? (Other than restart from a new fresh profile if it's possible…). I confirm that all the extensions are functional and activated. Thanks,

Emeric

Firefox worked perfectly, but since a few days I can't download anything. I'm using Mozilla Firefox snap for Ubuntu 22.04, version 110.0.1 (64 bits) canonical-002 - 1.0 With Chrome everything works perfectly so I assume it's a problem from Firefox.

When I open a PDF, a MP3 or any file, the "save" option doesn't display anything. Usually it opened a dialog where I could choose the folder where I wanted to download the file, but now I have nothing.

I have only 4 extensions: - adblocker ultimate - duckduckgo privacy essentials - vuejs dev tools - zotero connector

I always had them and I never encountered any problem.

Is there some way to hide all the menus at the top like F11 does, but still keep the total size of the window unchanged? I would like to look at webpage in "read mode" on for example the left half of my screen.

Hi, I have firefox on my Ubuntu 23.04. When i start it it shows a black screen. I click quit on my system and then i startup and it lunches normally. What am I doing wrong or how to fix it?

If you can find out what causes this error code to appear, we would be on the road to solving the problem. BTW, it can play videos on the selection screen but only raises the error when i try to launch the movie. I also have difficulty with News videos where the wait symbol never stops, it just keeps trying to play it and never succeeds.

Everything under Logins and Passwords, and Forms and Autofill is unchecked. A "Primary Password" has never been set in firefox.

Can't get it to stop asking, which is made worse by the fact that nothing is selected to prompt it nor is anything stored for it to use.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

Sometimes when a a browser add-on is having trouble, I removed it, then hit undo, and sometimes it works again after that adds it back on. I thought I'd do that today since some were showing blanks instead of their icons. I did one from the manager just fine, but when I removed one from the toolbar instead of the manager, no undo option was presented, and I don't recall which it was. How can I undo, or view recently removed extensions?

When I click ctrl+q by mistake, the browser window with all its tabs is closed immediately, with no warning. This has already made me lose data. is there a way to disable this keyboard shortcut?

I want to use a local html file as my new tab page. Currently there is no easy way to do this as far as I can tell.

Firefox at some point has removed the in-built option to set the new tab as a local file. Setting the home page as a local file is possible. But setting the new tab as either home (note, not 'Firefox Home') or explicitly the local file is not an option (see attached image).

Previous forum posts point toward New Tab Override extension. However, in recent releases, add-ons cannot offer a work around as Firefox no longer allows add-ons to access local files. In the image attached, New Tab Override extension shows that it cannot use a local file as the new tab. It can however take a file and store it somewhere it has control over. This means every time I edit the local file, I need to manually re-upload this to the extension in each instance of Firefox. It is no longer a good option.

I am sure I used this feature not too long ago and it feels like a very simple thing. I am sure I must have missed some setting or option. Any help achieving this would be greatly appreciated.

I just updated Firefox to version 81.0 in Linux, Windows and Mac, but the credit card autofill option is still missing from the Preferences menu.

I followed the instructions from here:

Hi! Does anybody know how to disable browser closing by ctrl+q shortcut? It is too close to ctrl+w and sometimes I close the whole browser instead of one tab. Moreover it is really useless and stupid feature since I have alt+f4. Why I need another shortcut which do the same stuff? And why developers ignore this issue which was reported on several forums? I tried install extension which disable it but it doesn't work for me.

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

The question at the following URL has an answer that is no longer the best answer, but it is Archived and I cannot provide the better answer. Since "How can i reset 'container defaults' in FireFox Browser? I.E. I previously selected to open a certain 'site' is a specified 'container' - now I want to clear." is the top hit when I look for this on Google, I'm attempting to provide the answer here.

Dear Community,

I would like to download this extension: https://addons.mozilla.org/pl/firefox/addon/adblock-plus/ I would like to know how it works. If I will install this extension my firefox will be check hashsum for the files of this extension automatically? Or maybe public key of the organization/company who created Adblock Plus extension? How it is work? Can you tell me? I hope that people from Mozilla now read this and can answer for my question. This is very important for me.

Next question is to Adblock Plus extension. I can read this information: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing" so my question is why Mozilla don't recommended this extension? This extension now use 6,678,297 people so this is huge count. It is possible that this extension is not safe and these people now use malicious software? Why on dedicated website for this extension I can't see company name? Why this company is not verified by Mozilla? So my sugestion for people from Mozilla is to change this and check this extension or maybe add some information on website for this extension.

So I should install this extension? My friend use this on Google Chrome and he recommended me this software but I don't know if this is exatcly the same version. Maybe Chrome has verified Adblock Plus software and this is safe but Mozilla didn't verified this and this can be dangerous software because this can be not exactly the same version?

Next question is to adblocker. Why Mozilla can't make their own software to block all annoying ads and due to fight with malware? Example Opera browser have own buil-in adblocker. Why firefox can't do this? Maybe people from Mozilla should do this? This can be helpful because if this can be happen I will be not install any 3rd party software for firefox anymore and I will be safe. Maybe I can send somehow this suggestion to people from Firefox?

I hope that you can help me.

Yours faithfully, Peter

When I download a file and click on the downloads button to bring up the Downloads menu, I often just want to open the Linux Mint file manager in the right folder so I can move the file to a more appropriate place.

In the menu, there's the little button to the right of the listed downloaded file with "Open containing folder", but if I click on that, FF opens the downloaded file, not the file manager.

Obviously this wasn't always like this, but I don't recall doing anything that might have caused the issue. How can I set FF back to the default action of opening the Linux Mint file manager?

Thanks!

I was following this reddit thread on how to remove the "your camera and microphone are being shared" popup, but it's having no affect.

I have set `toolkit.legacyUserProfileCustomizations.stylesheets` to true.

Here's the full contents of the userChrome.css file: ```
