Firefox Support Forum

Hello guys,

I just got a new M2 SSD and I just decided to reinstall Windows and everything on it. However, when I installed Firefox I started getting this exact error message on all twitch streams: "Your browser encountered an error while decoding the video. (Error #3000):. Keep in mind I have tried most if not every "fix" I've found. I've disabled the hardware acceleration, cleared cookies and cache, I've disabled the extensions, I've tried Incognito mode, I do not have a third-party anti-virus and I do not have a VPN. This works on all other browsers and it used to work on Firefox before I wiped my PC, so that I can install Windows again. I really do not want to use a different browser, I love everything about Firefox right now.

Any suggestions will do, thank you very much.

Prior to the last update, Firefox was auto resizing my tab background area (I don't know the technical name of this, but its the menu area behind the tabs) to fit more tabs as I opened them, up to a certain number of open tabs. Now the tab background area remains at its full size from the start even if I have only 1 tab open. I prefer the old behavior and I'm not sure what userchrome setting I need to adjust in order to get back to it. The line that is causing the issue is as follows

1. main-window {

 /*--tab-min-height: unset !important; */
 --tab-min-height: 38px;
 --tabs-lines: 8;     /* THIS LINE CAUSES THE PROBLEM */
 --tab_min_width_mlt: 186px;
 --tab_max_width_mlt: 186px;
 --tab-min-height_mlt: 38px;

}

I can reduce it to a lower number but when I do that I am stuck with the tab scrolling behavior that I don't want. Perhaps there is a setting to auto resize the tab area that I'm unaware of. I would appreciate any assistance. Thanks.

I suspect that my bank tried to show a verification pop-up while I was on a third-party site, and because pop-ups were disabled the third party rejected my request. My question is:

How much of my bank's website address do I need to put in the "Allowed Web Sites - Pop-ups" edit box, seeing as I wasn't on that website at the time. Would "https://name-of-bank.com" be sufficient? Or, are wildcards allowed in the URL?

I want to dismiss one shortcut out of the two rows of shortcuts on my homepage. When I left click on the three dots on the Google Translate shortcut, and then left click on dismiss, the shortcut blinks and remains.

Hi, I'm using 0penlayers and with this online example : https://openlayers.org/en/latest/examples/export-map.html when clicking "Download PNG" button I get the following message in Firefox console : "Blocked https://openlayers.org/en/latest/examples/export-map.html from extracting canvas data because no user input was detected." And the image downloaded is incorrect. I have no Firefox user message asking for permission to canvas access. I'm using Firefox 107.0.1 (64 bits) Mozilla Firefox Snap for Ubuntu canonical-002-1.0

With Firefox on windows or android the example is working fine. On the example web page there is the javascript code using the canvas.

Bye !

Pierre.

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.

Can't log into router. Works with Chrome and Edge 192.168.2.1

Tried this says in the router's Admin page: Access setting page via https://router.asus.com:8443 * Please use port 1024-65535. With and without :80 and :433

Tried everything I can find on this site and Google. Has worked for many years.

I am currently having problems with my Firefox browser. For example often if I type something into the google search box at the right of the address bar and hit return nothing happens until I go down and select Bing instead of the google setting. Also in hotmail (I am on a desktop) if I go to reply, the original is now ether twice. This does not happen if I use Google browser. But I prefer Firefox as I have used it for years.

My concern is if I delete Firefox and reinstall it, I may lose some of the settings or bookmarks that I have set over the years.

Any suggestions? Please simple as i am old and not computer savvy.

Your help would be so appreciated. I am currently on Firefox 107.0 (64 bit)

Thanks, Anthony

make the dark mode come up in dark mode.

Even this page of yours is light not dark. I is not dark, but the mode is set to dark and the add on is set to dark.

if you cannot solve this then take away the dark mode that you pretend to have.

perhaps i should remove the dark mode add on, and use just the firefox built in one only. currenly both firefox and the firefox addon are set to dark and it keeps changing google.com to white when google settings are set to dark, then firefox turns off google dark mode and makes it white.

the version data you state below is correct. 107.0.1 win 10

it is now time to give up on firefox and use edge since their programmers are trained and professionals. your programmers can be anyone, which in fact make it the least secure browser. after 107 versions you still don't get it right. you don't really have a dark mode you should actually test your software.

google is my homepage and its setting is set to dark mode, but when firefox which is also set to dark mode always google comes up immediately in white mode and the google setting has been changed by firefox to google's white mode. stop changing google's mode, you do not have the right to do this. if I open a second tab it may up dark, it is not consistent.

Hi. I have experienced some font encoding problem occurring in the latest version of Firefox, not in previous versions. My system is Mac OS Monterey 12.3.1 and Firefox version 107.0

On some sites the fonts looks totally garbled (see provided screenshots). Disabling "Allow pages to choose their own fonts, instead of my selections above" in Firefox settings fixes the problem, but then all websites I visit displays with default fonts and not as intended. Moreover, I'm a web designer working with the built in web developer tools, and I need to see the correct fonts when developing.

Hoping to get some help with this issue.

With the latest upgrade to Firefox 107.0 there is no option any more to import or manage certificates. Going to Settings/Privacy & Security/Certificates and selecting View Certificates results in a window showing installed certificates with only OK button at the bottom of the window. No option to import, delete, save or anything else. OS: OpenSuse Linux 64bit

Firefox not loading and missing VCRUNTIME140_1.dll preventing re-installation. Full message is: 'The code execution cannot proceed because VCRUNTIME140_1.dll was not found. Reinstalling the program may fix this problem.' Tried to install an old version of Firefox (28.0) but this is not upgradeable.

I use the userChrome.css file to take the search bar from the bottom of the screen and have it float. Here's the instruction that I use ... .browserContainer > findbar {-moz-box-ordinal-group: 0; position: fixed !important; }. Firefox 107 has made that .css instruction non-executable. If I text out the instruction I now get the search box at the bottom of the screen. I want it back to a floating search box. Is there a fix in 107 so I can use my .css file or is there another way to get the search box floating. Regards

More and more websites are alerting me that they are not fully compatible with Firefox and that I should instead use Chrome, Safari or Microsoft Edge. Recent examples are Allstate Insurance and Hewlett-Packard, not exactly insignificant players in the business world.

Here's what Allstate had across their page when I was attempting to log in:

"You may not be able to use certain My Account features on your current browser. For the best experience, consider using the latest versions of Chrome, Safari or Microsoft Edge."

There have been other websites with similar messaging about Firefox. The issue seems to be growing. Is there a fix coming from Firefox or are we going to continue to lose compatibility?

No Video with Supported format and MIME type found is not allowing me to play videos on website.

No idea what's the cause of it, I've tried everything from internet tips how to solve this.

The minimum size of the Library panel has been getting larger and larger. It can no longer be resized so that it can be fully visible on the desktop when other windows are open to 1:1 size. The issue first started nine months ago. It was troublesome then, forcing me to use extra hand motions and mouse clicks just to get a fraction of a seconds worth of information.

In other words, Firefox has made it more difficult to retrieve important information that used to be available at a glance. I have determined that Firefox has rewritten their programming to intentionally do this to us. WHY?

Please make the Library Panel box fully resizable again. It is becoming a make or break issue for me. Stop tinkering around. You had perfection, now it is ruined. I do not want the window buried, partially obscured, or on top of any other window. It should have equal rights with other fully resizable elements.

how is it that the usps website works on edge, but not on firefox? usps stopped working about a month ago on firefox. i already tried clearing the cashe and cookies from usps and that did not work, and neither did turning off ad block plus. im at a loss here.

I have Firefox 107.0b5 (64-bits) Snap for Ubuntu canonical-002 - 1.0 I use Ubuntu Mainline to update to newer kernels. Never had any problem doing that. I am now on 5.19.15. But when I upgrade to kernel 6 (which is now at 6.0.5) Firefox tabs crash. Reloading doesn't help. Each new tab I open gives the same crash message. I have to restart to get Firefox going again. So I removed kernel 6 and reverted back to kernel 5.19 and have no problems any more. But question, what is the problem between kernel 6 and firefox? Does anybody else experience this problem?

I have no other problems with kernel 6 with other programs or hardware or whatever, only firefox tabs crash...
