Hello

I want to use extension xpi's from a shared external folder over multiple Linux profiles. So i examined the profile folder and found extensions.json. Though i can't find any documentation to it's keys online.

There's "rootURI:" with a "jar:file://path/to/extension.xpi!/", so i tried just replacing the path with the shared one. Though i observed that just makes firefox replace the path with the current one. So i examined further and found the "location:" key with the default value "app-profile". So my guess is, there's other values for other usecases, right?

So, in summary, what i need is:

• documentation to extensions.json keys or possible values to "location" key.
• if that isn't intended/doesn't work, how i can achieve my goal otherwise.

And please don't suggest the sync feature, that doesn't work for my usecase.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

Hello, I have the fallowing issue with Firefox and the sound icon on taskbar in Windows 10 22h2, when Firefox is open and I click on the sound icon on the taskbar in Windows 10 22h2 the sound icon does not open, when Firefox is closed the issue is gone.

Any help to fix this issue would be great.

Thanks

Matthew

In all instances, when I click on a link to view a document on a website, rather than simply pop up to view, the document is downloaded and I am required to save it to my computer. Something in the Firefox settings is preventing the pop-up view from occurring. Not certain where to reset in order to correct this. Please advise

Is there any way to make Firefox iOS browser Dark Mode a little darker by avoiding the moments when it is loading or reloading a page and the screen is fully bright white?

Always shows "Failed to check for updates" On version 125.0.3 and still says needs to be updated. Then just run the install again and then it stops for a bit still on same version and then shows up needing update...been doing the same thing for a while now.

The Copilot website text field is the only text field I have encouraged where typing text does not get automatically underlined for spelling mistakes. I have the box ticked for 'Check your spelling as you type' in the general settings, and I have tried changing the about:config layout.spellcheckDefault value to 2. Nothing has worked.

The spell checking feature for the Copilot website text field can be enabled, but you have to manually enable it each time by right clicking the text field and making sure "Check Spelling" is ticked. It is quite annoying.

The "Check Spelling" setting on every other text field from every other website like this very text field I'm typing into right here right now for this firefox support forum, has the  "Check Spelling" setting ticked by default.  

Anybody else experiencing this issue?

HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP!

Hi Firefox. I have been using Firefox since the 90's. I love the feature that you can save a url complete with that website name, icon, and colors. My desktop is very colorful. I just did an update on Firefox in the last two days. Lets just call it the last update. After the last update an hour ago I just received a notification that Malwarebytes blocked what the call Malvertising. As I said, I have been using Firefox since the 90's as my default browser and I have never seen this before on any browser. There were an few short periods in the last few months when Firefox would just lock up my pc, and I switched browsers to Chrome. But as soon as you corrected the issue, I switched back to Firefox. I got to admit that this Malvertising notification has disturbed me a little. I have Edge, Chrome, and Opera browsers installed as well but I like you the best. Please explain to my why I got this notification from Malwarebytes. BTY, Malwarebytes found a keylogger in my PC that Eset, and Windows Defender scans did not find. So, I am a fan of Malwarebytes as well. I downloaded the Malwarebytes notification of the Malvertising Notification into .txt format, but the button below this says images. If I can send it, and you want it, just let me know.

Can someone please answer how to reset firefox size after you've been using a bigger screen and go back to the laptop the top bar is lost way up and I cant catch it to move it to resize the firefox window. Using Fn and F11 to go into maximize mode doesnt help me at all cuz I end up in full screen on the FHD screen but cant grab and drag the window to resize it again - and please NO comments about using FN and F11 again. This is an issue thats been since years - cant figure out why ppl who are tryin to help think others dont know the difference between maximization and the window being bigger than the laptop screen and being lost. So FIREFOX key-shortcut for window size reset URGENT PLEASEEEE - Im having this issue couple times a week. To fix it I gotta go again to the bigger screen reduce the size of the window and then disconnect - which is soooo horrible.

Hi, Before Firefox's Version 125.0.1 (64-bit) latest update I could download any file from my safe office environment, behind firewalls, VPN, ... Now despite of unchecking the "Block dangerous downloads" I'm still unable to download files. I have Windows 10 on my laptop.

Here are the steps: Click on a file, Save "File not downloaded. Potential security risk." Click on the message - Allow download The result is a file with content "HTTP Status 405 – Method Not Allowed".

Please help me to work the downloading again. I am aware of the safety but I want to switch off this feature.

Thanks in advance for help, Tibor

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

Enivronment: OS: Windows 10 professional 22H2 Firefox version: "124.0.2 (64 位)", auto update is enabled, it should be the newest version. security software: windows defender

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!

I've got a really old MacBook Pro that's still running 10.13, and Firefox has started displaying a nag screen telling me that this version is no longer supported, and to install a newer version of MacOS.

Is there something in the advanced settings that will stop it nagging me? I now know it's not going to get any more updates, there's no need to keep telling me every 20 minutes...

(Note to the devs: a "don't remind me again" checkbox would be nice for things like this!)

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?
