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

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.

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.

Bes Regard, Josef

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?

Everytime I try to do a search in Firefox I get a Manuals Library page come up. Why is it doing this? I did a search not long ago for a user's manual for a product, and I guess I accidentally downloaded this Manuals Library. Now I have no idea how to get rid of it. There is no shortcut on my desktop for it, I cannot find it anywhere in my downloaded programs in Uninstall or Change a Program in my Control Box. I DO NOT want this program! Help please!! I tried to do a screen shot of the page, but your browse won't pick it up when I browse for the screen shot I saved on my desktop. Below is the web address copied from the address bar.

I hope someone can help! Thank you so much!

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

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?

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!

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.

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!

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.)

After upgrading to Firefox version 103.0 on Windows 10 I am no longer able to Login to https://auth.synchronybank.com/account/login . After entering my User ID and Password I stay on the Login screen with the gear spinning for several minutes then receive the error screen shown in the attached image. Clicking on Try Again" on the error screen produces the same error. Please correct ASAP.

Note that the Login from https://auth.synchronybank.com/account/login completes successfully using the Google Chrome or Microsoft Edge browsers.

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?

None of the menu buttons work at the top of yahoo mail in firefox when an e-mail is open, I am able to use these in Microsoft Edge. Until the last update of firefox they worked so something broke in the latest release 103.0.1 is my guess. I restarted without extensions and still broken.

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?

Hello

Since the latest version of Firefox I am unable to view obituaries on newspaper websites such as The Vancouver Sun, and The Regina Leader-Post.

https://leaderpost.remembering.ca/obituaries/obituaries/search?filter_date=today&sort_by=obitslastname_meta&order=asc

https://vancouversunandprovince.remembering.ca/obituaries/obituaries/search/?filter_date=yesterday&sort_by=obitslastname_meta&order=asc

They will work using Edge.

Thank you

everytime I open firefox, it automatically switches tabs like these which require authentication to log in. even though their password is saved, I am still required to click in sign-in button.

Its really annoying that these kind of tabs get opened automatically, and then I have to switch back. Is there a way to disable this autoswitch or better, let the authentication happen automatically since the password is already stored ?

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"

When I go to websites there are unusual characters(light font) that are displayed. That shouldn't be there. How do I get rid of them?

See attached screenshot.
