Why is Firefox backing up my bookmarks in a json file, when Firefox itself doesn't recognise the file type when trying to restore said bookmarks? I WAS able to restore my bookmarks by converting the json file at https://www.jeffersonscher.com/ffu/bookbackreader.html. But why can't Firefox just back up as an html file like to used to? I had to go off searching the internet for a solution, turning what should've been a 5 minute job into nearly an hour 😕

On a laptop running Windows 11, all videos I play in Firefox have been strangely dark and orange. Depending on their original appearance, this can make them unwatchable.

This only affects videos in Firefox, and only on this laptop. Chrome, Windows video player (and Firefox on my other devices) do not share this issue. The issue affects all monitors I connect the laptop to.

I have attempted: -A thorough search of Firefox settings and found nothing related. -Refresh and reinstall of Firefox -in about:config

   gfx.color_management.native_srgb to true
   Confirmed ui.videoDynamicRange was set to to 0

None of these has helped. According to all the evidence I can find online, a similar issue was caused by a problem with HDR video files and fixed in an update 2 years ago, but I am running version 127.0 and am up to date.

ALT-SHIFT-LEFT has been 'select word backwards' for years, at least on macs. And so it was on FF too. Now they suddenly decided to re-map it to 'select left tab'. There was already a key for that - CMD-ALT-LEFT. Which also works for the right, whereas ALT-SHIFT-RIGHT does nothin

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Recently installed a "cleaner" app called PrivaZer. Ran the app and rebooted as part of the process which also included creating a restore point. Once system rebooted and logged in, pinned tabs were gone?! Using the created restore point did NOT restore the pinned tabs. Is there a way to recover the pinned tabs? Thanks in advance. FRANK

We have a W10 workgroup using an unmanaged switch to hook 5 PC's together through hardwire ethernet. The switch is also the access point to the internet "modem".

I would like to cause the PCs to use wifi to access the modem ONLY for internet and Thunderbird, with the workgroup remaining on the wired system.

With both "networks" enabled in W10 the PCs are automatically defaulting to whichever method was enabled 1st. I have no idea how or if I can "split" the flow and cause FF and Tbird ONLY to use wifi.

There should be a feature where you can copy the link to particular text on a webpage (much like when you click on a Google result for a certain part of an article). Where do I suggest features for Firefox?

since the last update, the shortcut keys to highlight a word at a time left OR right are both highlighting the next word AND also jumping to the last tab. AGAIN! I noticed this was identified as a problem back around 2019 in a search. I now cannot move fluidly within text, nor highlight a word at a time quickly. Either it's whole line or simply a letter at a time... which results in a pretty incompetent, crippling experience. PLEASE FIX!!

Hey there,

during work I often open two windows of Firefox to have more information visible on my two monitors. Unfortunately I sometimes forget that I have a second window open, so I close only my "main" window and loose all tabs.

Is there a way to force Firefox to ask to close a window and loosing multiple tabs for every window open?

Right now this only happens for the last open window.

PS: I just found out about the keyboard shortcut of restoring a window (CTRL+SHIFT+N) recently. I would prefer a setting in my case.

Thanks in advance Fred

When I go to Settings > Privacy & Security the only "autofill" setting is to import data from another browser. I am signed in, in the US, and my VPN is set to Seattle.

If I open a second tab on the screen it says the connection has crashed and keeps doing it if you try again. If you reset it resets Firefox including the other tab.

Is there a way to create a new keyboard shortcut to copy current tab URL?

I've been using Arc to try some of their features, and what I miss the most is the hability to copy current URL to share without touching the mouse.

My old hard drive died I couldn't recover it. I cannot mount the disk to another OS etc. The session files cannot be retrived. However I had over 100 tabs open in Firefox I want to retrieve before the disk crashed. I was signed in to firefox all the time in the old computer.

I now have a new computer, I signed in to firefox and I can recover the bookmarks. But I don't see any option to recover the lots of tabs and sessions from my previous dead disk. It seems there is tab sync options between 2 devices that is concurrently signed in. But I can't sign in to a dead disk. I also can't recover the file.

How can I reteive my old sessions with many tabs? I'm hoping firefox have a way of knowing all my tabs since I was signed in and sync before the disk crash.

Hello! I have a serious problem. I lost access to my data because I changed my password, so my data is no longer synchronized. I reinstalled my Windows, and I forgot the old password I had on that Windows. As I reinstalled, I decided to change the password because I didn't remember it, but after that I found out that synchronization doesn't work. Please help me, I had very important bookmarks that were there. Thanks in advance!

Bought a new computer. All my toolbar bookmarks migrated across successfully. Sidebar symbol missing from the menu bar and I couldn't find where these Book Marks were at first. But then I right clicked on the menu bar, clicked on Manage Book Marks which opened a Library box and there they were. Does anyone know an easier way to access them please? Any tips gratefully received. Thanks, Bob

For some reason I notice that some of our image files, viewed after opening an online pdf document with images within, shows random white horizontal lines. This is not shown using edge or chrome. you can go here to view https://mcclone.net/wp-content/uploads/2024/05/Connects-Issue-12.pdf.

Any help would be appreciated.

Thanks Chris

Running Win 11 Pro with the Firefox - 64 bit - All updated per June 9th.

ISSUE: Website tells me I have an 'add blocker' or the product 'addblocker' installed. I don't. However I get blocked even viewing my own website: fleksjobbernetvaerket.dk .... and others as well.... It's full of Google ads.

SOLUTION: I searched for how to solve this, but none of it is working, not even re-setting or re-installing Firefox, emptying cache, files and folders. I kinda gave up on this.

Hope you can help.

thanks Knud

The lag is very problematic to me, because I do most of my work using the browser. When the keyboard starts lagging I can only enter text using copy/paste with mouse (which works fine). The only way to solve it is to restart Firefox (which can result in lost work).

The lag, when it starts, is 10 seconds or more for each keystroke. It occurs about once every few days.

Ubuntu 22.04.4 LTS

126.0.1 (64-bit) Mozilla Firefox Snap For Ubuntu Canonical-002 - 1.0

I don't use Wayland.

Setting accessibility.force_disabled to 1 did NOT help.
