Hello, when I click on link with middle mouse button it will open that link on next tab but doesn't "jump" there, which is fine. But when I do the same with pdf links, it will automaticly "jumps" on the pfd file. And I don't want to. I want to open it like normal link (on next tab in background), because I have a lot of pdf files to open, and this makes it difficult to do it qucikly. Before some weeks this wasn't a probem, it started now.

When printing double-sided from Firefox 103, the second page comes out upside-down. A previous thread 'Two-sided printing rotating on wrong axis' reported this problem for Firefox 85 / 86, and said that it was fixed by updating to the current version. I have the current version, but am getting the same problem. I have tried manually setting instructions to flip on long side (portrait orientation), but that doesn't work. Help!

OS - Ubuntu22 Firefox - Default firefox on ubuntu22 (Mozilla Firefox 103.0.1)

Use case - 1. Custom profile folder (named prof1) contains pref.js and chrome folder with custom css file. 2. prof1 is created in -> "/customData/profiles/prof1" 3. The folder "/customData" has full rwx permissions and is owned by $USER (not by root)

Output -> 1. When launching firefox mentioning the profile -> "$ firefox --profile /customData/profiles/prof1"

The browser does not load, but there is an error box saying Profile Missing Your Firefox profile cannot be loaded. It may be missing or inaccessible.

Questions -> 1. Is it possible to load firefox profile from root directory ? 2. If custom profile folder is created in "/home", then it is launching and working perfectly. How is this possible when the permissions and owner is same as the one in "/customData"

After update of Firefox version 103.0.1 the symbols are too big and the size cannot be reduced (to small size). So too few symbols fit into a symbol line. How can this be fixed?

I had problem with Firefox. He was slow, i reseted, but my addons disappear. Now i have problem, i can install any addon's. Doesnt matter, official or unofficial. I cant anything. Firefox was again reseted, uninstalled and again installed. No matter what i do, come this massage:

"Installation aborted because the add-on appears to be corrupt."

How do I add a site in setting - camera permissions to allow it to use my camera and microphone while still blocking other sites from asking to be allowed to use it.

Until FF100, I used to disable <Ctrl><W> (close tab) by modifying browser/omni.ja, commenting the following line out in chrome/browser/content/browser/browser.xhtml :

<key id="key_close" data-l10n-id="close-shortcut" command="cmd_close" modifiers="accel" reserved="true"/>

It worked until FF100, but doesn't work anymore in FF103 : commenting that line out seems to have no effect on <Ctrl><W>.

Does anybody know why ? Or does anybody know a way to disable <Ctrl><W> ?

Background : on French keyboards, the <W> key is right next to <X>, so when I try to do a cut/paste (<Ctrl><X> → <Ctrl><V>) I sometimes end up doing <Ctrl><W> by mistake, thus closing the tab. Re-opening the tab doesn't always do the trick, sometimes the latest work is lost.
