How can I restore a previous theme? I had a "colorfore" theme that Mozilla offered a few years ago set up in Firefox. It was perfect! I could see everything clearly with my aging eyesight.Then one of my synced computers needed a new Linux OS installation so I signed out of sync on that machine. Installed the new OS. When I started Firefox the first time I signed into sync. I got my history, bookmarks and bookmark bar, but no custom colors. Now my computer at work has its colors reset to the out of box colors too. I have lost the colorfore colors I have been using for several years now. How can I get the colorfore colors back? Thank you for your attention in this matter. I love Firefox, use it exclusively and contribute to Mozilla. Gregg Scholfield

Example of what i want to do:

I'm browsing Website and i click and open a link. Examples:

https://Website.com/P/-this-site-doesnt-exist--68290.html or https://Website.com/P/-this-is-also-an-example--34846.html


I want Firefox to automatically delete "-this-site-doesnt-exist-" or "-this-is-also-an-example-" whenever i open any of them. So opening them would instead open:

https://Website.com/P/-68290.html or https://Website.com/P/-34846.html

Can this be done?

I'm trying Firefox again after many years in the Edgy wilderness. In Firefox in Windows, you used to be able to specify where your bookmarks were located. I store all my files (documents, spreadsheets, etc) in a complex structure on my C drive and, ideally, I should be able to store my Firefox bookmarks in the same structure. It just doesn't make sense to store the bookmarks in a separate location. I'm pretty sure you used to be able to do this by specifying the root of the bookmarks structure as c:/Documents, but I can't see how to do it in the current version.

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!

Hi, After latest update (123.0) usernames and passwords are not auto filling.

- I noticed that "Ask to save passwords" is unchecked and not configurable(or grayed out). - I tried troubleshoot mode and did refresh too, no use. - History setting is set to "Always remember history".

Note: I see the banner: "Your browser is being managed by your organization.", There I dont see any of these settings controlled except primary password is turned off.

I had to Restart/Refresh Firefox because I lost my dropdown menus and then the Google Search bar in the right-hand corner disappeared. Somehow I got it to reappear but it's too small. I followed steps in several different posts and can't get Google Search Bar to widen. 1. I placed the mouse pointer between the search bar and the address bar and nothing happened. 2. The following didn't work for me because I can't find the “Use Small Icons” box: "Click the “View” tab on the program menu and choose “Toolbars.” Select “Customize” from the fly-out menu and a “Customize” toolbar screen loads. Deselect the “Use Small Icons” box and click “Done” to enlarge the icons on the Firefox toolbar." I attached a screenshot of what FF Browser looks like.

Just downloaded Firefox a day ago; since a friend told me that its better than Edge. It seemed fine at first and then went and looked at task manager. It's using way more memory than Edge. Firefox has 19 separate tasks running totaling to ~1,500 MB. I need to know what I can do to lower it. My friend made it sound like Firefox was way less memory intensive. I don't even keep 10 tabs open at a time. Any help would be appreciated.
