Firefox Support Forum

Hello! I've created a custom theme in firefox color, and I'm getting an error trying to upload it to the add-on developer hub. I downloaded the .xpi file and tried uploading it, but it only says Your add-on failed validation with 1 error. Received an empty response from the server; status: 403 I'm wondering how I can fix this, or how I can at least find my design that I saved within firefox color. I clicked on save, but when I tried making a new design in firefox color, it removed the old one. Now I'm having trouble finding my creations! If anyone can help I would appreciate it greatly :) Thank you. And as you can tell I am new to firefox color.

Dear Firefox, It is a matter of great regret that your popular browser has failed to sync back my saved bookmarks and other data once i reinstalled firefox. This issue is not new as it happened to me before.. Last time I didn't bother as I thought this might be an bug but today once I reinstalled firefox and signed in.. It seemed that firefox has yet once again failed to syn all my bookmarks, data, extensions etc... It is a huge pain as I cant keep on repeating myself to save all the extensions and preferences.. please solve this issue or I wll have to seek other browsers

I recently bought a drawing tablet for some editing and I edit pictures on a website but every time I move the pen vertically on this browser it scrolls up and down accordingly and so far none of the settings have been helpful for stopping this.

This is in the address bar when I open a new window; chrome://branding/locale/browserconfig.properties This is the message I get and have to open a new tab: File not found

Firefox can’t find the file at jar:file:///C:/Program Files/Mozilla Firefox/browser/omni.ja!/chrome/en-US/locale/branding/browserconfig.properties.

   Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

Why do I keep getting this instead of a fresh new window? It is annoying to have to open a new tab after a new window.

Hello,

Is there a way to force bookmark icons to show up in the web browser? I need to know, as it really bothers me to have the grey globe icon showing up. Thanks,

Brian

I have been using firefox for quite some time, and have bookmarks and addons saved to my account. I just recently had to restore windows on my PC, and in doing so, seemingly lost my whole profile. I also have firefox on iOS, and all of the bookmarks are saved there, apparently on the same account I am using to sign in on desktop. I have tried to force the desktop version to sync, but it says it has fully synced and none of my stuff is here still. Is there a way for me to import the profile from iOS or something?

When I first open Firefox and go to my yahoo home page - I can pretty much open any page - 1st try. However, after I leave a page and try to return - no luck. Has been doing this for the last 6 months. Using Firefox on an updated Macbook pro. No problems with Safari.

So i've found this thread but it's not the solution I'm trying to restore text written as YT comment ( but YT deleted it ) Found it in a cache but it's a "secure document" and "expired immidiately" Is it possible to recover it ?

Had to refresh Firefox but lost my bookmark sidebar & can't find a way to re-establish it. Used to be a setting for it at the top of the home page but none now. Can't find it in settings.

I used to get images off web pages easily, now I just get an html link, which when I try and copy to powerpoint presentation, just gives me the link address and not the image! Very slow and unusable in the end. please help me to get to jpg or png as before.

Long story short...I lost my hard drive, reinstalled windows....I never used a firefox login on this laptop. I do have a backup of all my data/appfiles --- actually i cloned the failed drive. So I have this directory in my backups:

D:\Users\USER\AppData\Roaming\Mozilla\Firefox\Profiles\810aqnu7.default-release-1636153011215\bookmarkbackups. There are a bunch of JSON versions of bookmarkfiles there stored....how can i get my bookmarks back with these files?

where is the "current bookmark files" stored? which directory?

thanks in advance.

bold textI need to sync my phone to my new computer so I can get my bookmarks and passwords transferred over to my new computer. I am afraid to scan the QR code because it reads as if it will sync this empty canvas to my phone and wipe all of my data out. What steps do I need to take?

Why did you all of a sudden completely eliminate tabs? I don't want to have to click a drop-down menu to view my tabs, or now have to right click on a tab in menu to delete one. I just want to see tabs, as they normally should be, all lined up in a row when I look up at my screen. WHY did you change this?!!

Whenever I open Firefox in MacOS Ventura (13.0.1) it opens in full screen. I want it to open a bit smaller so I can see my desktop behind it. Full screen is fine for a laptop, but I run it on a 26" widescreen monitor. How can I set it so it only covers, say, 3/4 of the screen?
