There seems to be no possible way to change the shortcut for peeking at the tabs in the sidebar (when sidebar revamp is enabled) from the about:keyboard UI. I have so far managed to modify the shortcut through intercepting function calls.

What I have done: 1. Read through the JS source code for about:keyboard which says the shortcut ID is `toggleSidebarKb` 2. Added hooks to intercept `RPMSendQuery` calls 3. Modified the shortcut through devtools open on the about:keyboard page with the following snippet

```js await RPMSendQuery("CustomKeys:ChangeKey", {

 "modifiers": "accel",
 "isValid": true,
 "key": "S",
 "shortcut": "Ctrl+S",
 "id": "toggleSidebarKb"

}) ```

The way I am doing it is definitely a hack. I am not sure if I am missing something. Although the shortcuts for bookmarks, history, and GenAI chat sidebar are present, there seems to be no entry to change the sidebar toggle shortcut itself. I'd love to work on this but I haven't been able to mach bootstrap on NixOS.

Thank you for any assistance :)

When I try to log into Tangerine bank I get the error. "We're sorry for the inconvenience. This function is currently unavailable. Please try again later."

This issue started Oct-13-2025 and it appears to work when using Firefox ESR 146.01 but not the regular Firefox 146.01 versions. Tangerine is not giving me information on the error and I was wondering if there is a difference between the ESR and regular version that might clear up this issue?

I have vertical tabs enabled and the "expand when hovering mouse" option is activated (see screenshot). However, the latter functionality tends to glitch at some point in basically every session. I can't tell if a specific action triggers it, so far it seems pretty random. The glitch is that either the tabs are expanded and won't collapse, or the opposite: they're collapsed and refuse to expand when I point at them. Is this feature maybe still experimental? or something? I'm running Firefox 149.0b5 DEveloper Edition on Garuda Linux (Arch based).

Back again with another question related to flightrising

there are familiars displayed next to the dragons, some of them are supposed to change their pose automatically, but for me they only change when I click on the familiar it works on other browsers, and on firefox for windows, so I guess it's something in about:config, but I have no idea what I'm doing, so I'm hoping someone here can help me figure this out, because I'm not about to mess around randomly

link to a page with a familiar that's supposed to change: https://www1.flightrising.com/dragon/80217294

pretty sure it's obvious what I mean by transform, and what I have to click on to get it to move, but I'm posting the pictures illustrating the change anyway

Using 148 on Debian trixie I do not see the option for "refresh browser"?

https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

Does it still exist or is there an alternative ?

Using firefox 148, when I select the "CIRA Canadian shield" DNS over HTTPS option it does not work. If I select the other 2 options Cloudflare or NextDNS those options work.

What is the problem with DOH for CIRA option ?

When accessing Google Docs, I can right-click and successfully Cut and Copy from the pop-up menu, but when I attempt to right-click paste, Docs pops up the message shown in the attached image. Ctrl-V works, but clearly Google Docs understands what is being requested and simply will not perform the operation, which is very annoying. Is there any way to get Google Docs to perform the mouse-based paste?

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?

I am using 140 ESR version on linux with Cloudflare's DNS over HTTPS and with DOH active for some reason resolving a domain like d3oklwo3y1bx83.cloudfront.net will resolve to local host IP 127.0.0.1.

I am using firefox about:networking#dnslookuptool to test resolution of the domain d3oklwo3y1bx83.cloudfront.net Both with DOH on and off the resolution remains local host. I tried another browser on the same workstation and I was able to receive a resolution of 13.225.193.203 13.225.193.133 13.225.193.64 13.225.193.58 Why is firefox ESR not able to resolve that domain? What are causes ?

Is is firefox dnslookuptool results.

Subject: Feature Request: Home Screen Widget for Favorite Sites ​Dear Firefox Team, ​I am a regular user of your browser and would love to see a Home Screen Widget for Favorite Sites/Bookmarks. ​Having a dedicated widget to access my top sites directly from the home screen would make the browsing experience much faster and more convenient. ​Thank you for your great work! ​Best regards, [Your Name] Burhan Ali

I get why the domain is highlighted, and it's good! But the rest of the URL can be hard to read, especially with dark themes (see screenshot, taken of this page's URL bar, using the default Dark theme). I have tried to find a dark theme with better contrast, but haven't had any success.

Is there a setting that I can change to set the font colors or contrast between them?
