Firefox Support Forum

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.)

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.

I've just updated my iMac which uses mac OS Monterrey12.5. As a direct result I can no longer use the Mozilla search window on the Foxfire Homepage. It's still there but it won't allow you to enter information into the box. Is there either a way to restore the functionality of the search window or at least disable it in settings so I don't have to see the window and be reminded that it no longer works? Thank you in advance for whatever assistance or answers you can provide.

i tried to play video from sites but an error is coming "libavcodec may be vulnerable or is not supported, and should be updated to play video."

my machine already have libavcodec installed properly.

i had downloaded firefox 103 for linux from your site and extracted it then running the command firefox.

as firefox have all the required files in one folder to run firefox web browser so mozilla have to put the libavcodec in the same folder.

i have another web browser installed from other firm and they provided me the media codec separately as per my requirements and it is working very fine.

so mozilla also have to provide me the media codec separately or put the media codec in firefox distribution package.

A few days ago, my Windows laptop was attacked by Trojan virus. Windows Defender totally disabled the laptop, and I could not even press a key. I had hard disk destroyed and the laptop, too. Because I intended to buy a Mac in a few months anyway. I attempted FF download twice, no luck. I think the M1 chip may not be silicon chip that FF supports.

Do you know a way to get my BOOKMARKS so I can export to Safari? Does FF keep them?

I have a backup of all my documents and I included bookmarks in that, on a removable hard drive USB3.0 The MAC doesn't have a slot for 3.0. Will require having to buy something from Apple to accommodate it.

Hate to do that if it's a fool's errand. I appreciate your advice. Senior citizen in over her head.

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

I am not a geek and I follow all the details of 'how to etc etc' but nothing works and the phone goes into random loops and keeps telling my I cannot sync (I KNOW that). Firefox has no phone number or email system for technical support (or any type of support) just this hit and miss system of 'forums' (or is that fora). I tried to send a bug report but I am NOT signing up for another (geek speak) account just to send you the problem. Please fix this issue - it never used to happen on older versions - how can I roll back my firefox to something that works properly?? Here is the error report, enjoy, to me it is written in ancient g(r)eek!

hi,

i'm using FF (version 98 at the moment) to print local files. It is key to me to edit header and footer for each print! the only solution i found so far to edit them at all, is to go to about:config and for example search for print.print_headerleft. Besides that is not usable at all, it simply doesn't work! The header and footer remain the same. Please tell me how can i change header and footer?

If you delete the, in my opinion much better "page setup", why don't you include all it's funktions in the new print dialog?

another problem is the size of the new print preview! it's much to small! make it resizeable please.

Or just give us back the "page setup". That would be a big advantage over chrome and edge, which suffer the same printing problems.

Thanks

The Washington Post website now loads in its mobile (rather than desktop/Windows) configuration. This didn't happen before the update to 103.0.1; it doesn't happen on my other computer, which is still running 103; and it doesn't happen on Chrome.

Until this is fixed, I'd like to roll back to 103, but I don't see how to do that. The "Install an older version" help page ([url]https://support.mozilla.org/en-US/kb/install-older-version-firefox/url) offers only v. 102, and the long list of previous versions ([url]https://ftp.mozilla.org/pub/firefox/releases//url) stops at v. 99.

Thanks!

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 some search engines which was configured a lot of years ago (or maybe was imported from another browser many years ago). They are working in address bar (e.g. I can enter there "cve something", press Enter and get redirected to https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=something), but not listed neither in about:preferences#search nor in my profile's search.json.mozlz4 (I've unpacked and checked it - it contents does match about:preferences#search). I've tried to grep for "cvekey.cgi" in my profile folder but get no results (I suppose these "hidden" search engines are stored in some sqlite file).

I'd like to have these hidden search engines listed in about:preferences#search. I can even manually re-add them, but how can I find complete list of all configured search engines?

I'm testing FF102 for rollout in September and working through various issues. The latest one I've come across is the edit bookmark "button" on the right of the URL bar. It's a blank space on the URL bar, and when hovered over is a highlighted blank space. After clicking it twice it displays the Edit book mark menu.

How can I remove it completely? I've look at about:config and nothing stands out as obvious to me controlling this and I can't find a setting for it.

The image below shows the highlighted blank icon space.

This code in userChrome.css worked in FF91 but only hides the icon in FF102.

#star-button { display:none !important; }

Thanks

Recently, when I was using firefox-nightly, the antivirus software prompted me that several virus files of type 'virus.js.unsafe.2' were detected in the 'entries' folder of firefox.

But I don't know where the virus is coming from for now, it could be an extension or a TamperMonkey plugin. so now I want to understand what the files in Firefox's entries folder do and where they come from?

I’m a Chinese. Sorry for my weak English levels

At some moment I´ve got a pretty big sessionstore file (6,6 Mb) which does not load properly. I´ve tried a few of FF versions and settings. My current version 103.0.1 64 bit loads it for few minutes and crashes when tabs appear. Some older versions loads it but after that have various problems with program interface: new tabs sometimes won´t open, no float tips when I´m hove cursor over tab header and so on. Also in such cases browser often crashes and not update old sessionstore file. I have 16 Gb of RAM, FF takes up to 5,5 Gb before tabs appear for moment and FF crashes. I have such big sessionstore file earlier (for example, 24.07.22 it has size of 6,5 Mb), but all worked fine. Maybe there are any internal setting that I have to try?

I've tried post in the thread 1287660 but it was closed. So, I opened this thread to continue about this subject and to answer the last question of the thread 1287660, at the same time. I was looking for about this subject and found the solution in the thread 1287660 - https://support.mozilla.org/en-US/questions/1287660, but the link of v9.7.2 quoted there was shortened and it is not working to download the 9.7.2 Fox Reader version. I found the complete link address: http://cdn01.foxitsoftware.com/product/reader/desktop/win/9.7.2/AC910684AD18B7FBD6E086B1211F7B4B/FoxitReader972_L10N_Setup.exe

P.S.: I am newbie here and I don't know when the 1st post is the solution at the same time.

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 ?

Zorin16-Linux version 99.0 Ubuntu Canonical 1.0, -found in Help/About. Firefox recognition of version below says 91.0. Also have Linux Mint 19.3 (Tricia). Computer 15YO Dell Dimension 900.

I've had no problems with Linux Firefox for many years. I do not use any other Non-Linux OSes. Linux Mint updates Firefox regularly and so do I in that OS. I'm currently in a free version of Zorin which doesn't seem to push out updates, so my Zorin Firefox may be sadly out of date.

At any rate, today in Zorin, when I went to several of the bigger online sales platforms, they refused to accept my Firefox and suggested Chrome, Opera, and Safari; Target suggested Firefox.

Went to Mozilla to try and upgrade, but it didn't offer the Linux browser automatically when it read my computer. I was only offered the Windows browser. This may be because the computer is an old Dell Windows machine that I converted to Linux or it may not. I've never had this happen before.

Yesterday in Linux Mint, in which Firefox is upgraded at least weekly, the same thing happened once with a big online retailer. They said my browser was outdated and unsafe.

What's going on? I'm wondering if Linux OSes are simply not being accepted when the big retailers are doing software upgrades, or is something going on with Firefox?
