How to stop Firefox from going to an already open tab when trying to open the same site again ?

yes i want 10 tabs open on the same site, stop switching to one open tab. i discovered i hold shift/alt ti prevent this, there must be an option to disable it altogether, how?

I run Firefox on a Dell laptop running Windows 10 Pro. I had to rebuild my system because of problems I couldn't solve. I've reinstalled Firefox and copied a profile I had saved in the cloud. When I click the extensions button ("puzzle piece") I do not see the extension list, only the add-ons page. do I have to uninstall and reinstall each extension to get it into the panel so I can pin some of them to the toolbar?

I have a current version of Firefox (v123.0 running on Windows 10) but I can't do what I used to be able to do? (And it is making me nuts!)

I used to be able to resize the contents of a site - such as youtube or wordpress or tumblr - there would be a little % on the far right of the URL bar, and I could adjust that until the site was readable and all the pieces I wanted fit in. I can't find a control that will change this for me in the new version. Is it somewhere else? Did that control not port into the new version? Is is gone for good? (I really hope not!) I realize this is such a small problem, but it affects how I interact with basically every site online.

What makes this extra frustrating is that I'm not even certain I am using the correct terms for the thing I want -

Thank you for your patience -

Hello there!

I have been trying to edit an existing browser extension (for the sole reason of adding new features to it for myself), and I've been trying to add it to my Firefox browser. However, upon trying to install it to the browser, it throws an error saying: "Installation aborted because the add-on appears to be corrupt". I've been trying to read more into this issue all across the internet, but none of the recommendations seem to be working.

I tested my extension locally and with using the about:debugging temporary add-on method, and everything seemed fine.

I tried to re-configurate the 'xpinstall.signatures.required' variable by setting it to false (even thought this method is considered unsafe in most cases), and the issue still occurs

I also tried adding a new gecko ID to it as stated in this article, but to no avail: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/browser_specific_settings

And last, but certainly not least, I tried compressing the extension with web-ext aswell.

My question is - is there a way to add this extension permanently to my browser without submitting it to Mozilla? I did not create this extension, I only added custom integrations to it for myself.

And more importantly - is there a way to add it to the basic Firefox browser, which is not Firefox developer of Firefox nightly? Or maybe create a desktop shortcut that will always start the browser in debug mode, always containing the extension as "temporary"?

I can see that many posts and questions have already been posted regarding this "custom add-on" topic, but my situation is a bit different since my goal is to only use this add-on by myself (and I'm also revisiting this topic since none of the previous suggestions worked in my case)

Any comments, helps, or even links would be greatly appreciated! Have a great day!

When typing if I make a mistake I'll usually just delete the entire word and retype it rather than fix the spelling but to do that I need to use CTRL. Now when I press CTRL it zooms in the page even though there are no other buttons being pressed.

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

How can I disable the ctrl+t shortcut? I have tried using the Shortkey add-on, but it will not touch the ctrl+t shortcut. It works for everything else, just not that one. I've been told I can modify the browser.xhtml file inside the omni.ja file, but I am finding that almost impossible. Has anyone managed to do this?

What the title says, and unfortunately I'm not sure why. If a theme isn't perfectly looped, it's...really noticeable. And I hate how ugly some themes turn out as a result. I don't want to start sticking my hands directly into firefox's advanced settings, since I don't know much about them and don't want to risk accidentally deleting or messing with something important, but I'd really like to get this fixed somehow... Is it just the themes I'm picking? Are they supposed to all be skewed off to the side? Or is something off with my browser? Maybe my resolution's weird or something...?

I think this happened before in an older update where the CTRL+\ shortcut would not fill in fields or bring up the pop-up menu for 1Password 4.

The addon is still usable but it is a good deal more tedious. It also seems like the prompts for new account generation do not show up, so all logins would have to be entered manually when making a new account, which is less than optimal.

If this could be fixed again this would be very appreciated.

Since the last FF update I can no longer see live streams from my axis cameras. Only a pic placeholder appears on the HTML page. FF on mac and win are affected. @the win pc the html website axis cam live stream works fine. after update FF the same problem as on the mac. cache clean done. Does anyone have an idea if I need to change a setting?

update : the html site use the following code : img src="http://XXXX1.dyndns.org:8000/axis-cgi/mjpg/video.cgi?resolution=320x240"

img src="http://XXXXX1.dyndns.org:7000/axis-cgi/mjpg/video.cgi?resolution=320x240" 
  

When I restart firefox, it works once and i see the live streams. when i open a new tab no live stream only the placeholders.

I'm trying to use a manual proxy server for Firefox. When entering the proxy address and port number, Firefox outlines the port number field in red and disables the OK button thus refusing to accept my assigned port number. I'm trying to use port number 29842 which was given to me by the proxy provider.

Firefox has a magnifier in the url bar. It activates for no reason. The arrow pointer does not move but the magnifier keeps going up and down 110%- 145%- 38% all over the place. only hitting escape several times and then touching the magnifier resets it back to 100% {normal} is there a way of eliminating this feature alltogether? Any help would be appreciated.

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

I have a home-built media center (OS: Linux Mint 20.3) utilizing Firefox as the primary browser. This system has run almost flawlessly for many years. Updated to 20.3 in early 2022. Rather suddenly (yesterday) Firefox began repeatedly crashing, displaying 'Mozilla Crash Reports' (example attached). Firefox appears to initiate as expected. However, on display (e.g., Youtube, Facebook, web page, etc.) request, Firefox immediately throws a 'Mozilla Crash Report'. I do not recall any changes to the system that might have generated this condition, and have spend most of today unsuccessfully troubleshooting.

MB: Gigabyte F2A85XM-D3H CPU: AMD A-10 5800K APU with Radeon HD Graphics OS: Kernel: 5.4.0.170 generic x86_64bits; on 128MB SSD Firefox for Linux Mint mint-001 - 1.0 (122.0 (64 bit)) RAM: 7 GB

I have attempted to follow some of the moz://a Support pages (i.e., "Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems"). I have noted that while in 'Troubleshooting mode', Firefox appears to behave as expected, seeming to implicate extensions, themes and/or hardware acceleration. However, under normal Firefox operation enabling/disabling these does not seem to resolve the issue.

    * Hardware acceleration (on or off) still results in display of 'Mozilla Crash Report',
    * Default theme is selected, and
    * I don't appear to have any unaccounted extensions or other addons enabled.

Any thoughts and/or additional guidance would be greatly appreciated.

This question was already posted and badly answered in 2016. Now things have changed a lot and Firefox DO try to translate everything which is quite annoying to anyone knowing more than a single language. No extensions related. I need to completely disable that. My firefox is up to date: 118.0.1 (64-bit).

Thank you Arturo

Hi, so here's the issue I have: Lets say you have 20 tabs open where the "tab scroller" becomes active and tab#17 has a video, if you enter & exit fullscreen on that tab then tabs #18-20 will slide to the right and go out of sight. This is quite annoying as I'd prefer all tabs on the right to be visible until I manually scroll to the left.

I tried googling for about:config or userChrome.css solutions but couldn't find anything, does anyone have any ideas on how to change this? Thanks.
