Firefox Support Forum

I have an odd issue with Firefox that has gone on for some time. Certain symbols don't show up correctly.

I've included an example with Google Calendar showing what I get with Firefox and the correct display using Chrome.

Is this some obscure setting that I need to fix?

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. Also, I've checked the 2 relevant items in about:config an they are enabled. How do I get the autofill to start working again?

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.

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've worked with Firefox for several years, and had it opening maximized. I recently manually resized the Firefox window to facilitate some work in which I needed some other windows visible. However, now I can't get Firefox to open maximized. Instead, it opens a window going from the left edge of my screen (see the first image below) about a third of the width of the monitor, and it is showing the double box icon in the upper right corner indicating that the computer "thinks" it is in full screen. If I click that double box, the window immediately shifts to the right edge of the screen, occupying a space about a third of the monitor from the right edge, and shows a single box in the upper right corner of the window. If I click that single box, the window finally does expand to full screen, showing a double box in the upper right corner. I've tried all the manipulations I've seen concerning starting screen size (such as going to the shortcut icon properties and indicating the that the program should start "maximized") but I'm still getting this same behavior. Any thoughts? (I'm running Windows 11, with the latest version of Firefox.)

I reset my PC and reinstalled Firefox last month, but my bookmarks were never recovered after I logged in my Firefox account. A couple of months ago I installed Firefox on another PC (to which I no longer have access) and it showed all the synced bookmarks, but this time it doesn't. What should I do? Thank you

I set up sync before reinstalling Windows 10 on my PC, currently everything is still intact on my iPhone, but gone on the PC, because I reset my password?

How can I get everything back in Firefox on my PC?

Excuse me, I realize there must have been many similar posts.

Using Firefox 103.0 on a Mac running Monterey. Since updating to FF 100.0 or possibly 101.0, the BBC News website's videos won't play. I've tried turniing off all privacy/security add-ons and settings but still nothing. Just a grey rectangle with the BBC logo in it (see screenshot).

Safari can play them though. Any ideas?

Since i have my new laptop, i do not get twitter videos, bbc news working. Youtube and vimeo does work! Guess its about html5? Have checked mediasource and javascript settings in about:config and they are okay. Do not have this problem in brave browser.

Anyone has an answer?

Thanks in advance!

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.

Duplicate. See https://support.mozilla.org/questions/1385117

Sometimes when I open a video it doesn't play, it infinite loads with a black screen and I tested it on a separate browser and the video works there

I've tried deleting cache and cookies but it doesn't work

frustrated and thinking about moving away from firefox. why not let us choose whether to update or not??

cookies deleting you have to search for each and everyone (why not sorted by installed date???) then one has to delete all the site cookies that are ok cause such a big effort to clear cookies!

no longer able to bank cause bank changed their cross site settings and firefox wont let me through...have to watch the status in bottom left corner and hope I can read it fast enough.

laptop always behaves like cell phone...can't read, can't see desktop properly
