Firefox Support Forum

I'm running 115.2.1esr x64 bit on Windows 7 pro. games on Facebook will not load I get 'Your browser does not support graphics API "WebGL2" error'.

In 'about:config' shows GL2 is enabled, yet Facebook games works with Google Chrome and MS Edge browsers, this seems to point to a Firefox issue.

I removed Firefox entirely, cleaning the registry etc, installed the latest version and get the same result.

Can anyone throw light on this? If need be I'll enclose

the troubleshooting info. 

Thanks, Dave

I have the same issue as stated in https://support.mozilla.org/en-US/questions/1390122?page=3

How does it come that it is still present in 117? Why is there no official guide or warning about this issue? I am forced to use Portable 101 where there are no such bugs. The solution in the thread is unclear and points to Microsoft, which is ridiculous. The question is how to solve that Mozilla's bug?

Suddenly, I found I could not access Wall St Journal through my public library website using Firefox: I had one-time accessed Wash Post through the same site vs. daily accessing WSJ and after that any access would lead me to WP and not offer WSJ as a choice. Per the public library advice, I switched to Edge and immediately could access WSJ per usual and did not have the problem as with Firefox. Why? I have also had some sites which could not be accessed through Firefox but only through another browser like Edge.

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Hi, My computer was having some issues and I thought that I transfer everything to a flash drive to transfer my information to a new computer. Come to find out it didn't transfer over to the flash drive. So everything is lost. My book marks and my saved web sites and passwords to them. I was wondering is there any way that you can help to retrieve them?

I use two monitors, and I have multiple firefox windows open at once. When I turn on my pc and open firefox, the windows almost randomly position themselves on both monitors, sometimes they are not maximised either. How can I change this behavior so that all my firefox windows open, maximised, on one monitor rather than both?

Your Firefox profile cannot be loaded. It may be missing or inaccessible

on debian 12 linux

I tried `firefox` `firefox-esr` `thunderbird``firefox -P`. I also deleted `~/.mozilla`, `firefox -p presaved-profile-dir` stay the same.

the `firefox binary` and the `profile dir` are all useful because I saved them to zip file and use them every day. So is there any other dir besides the 2 dir which fails the startup? even thunderbird fail with the same reason.

Help please, thanks!

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I have Mac Pro 2018 and having a problem with Thin Lines on left side of the browser (Firefox Mac) i can't find anyone on line with same problem explaining how they resolved the issue!

I'm trying to restore Firefox Bookmarks and stored login/passwords from a Time Machine backup of my Macbook Pro. I've read in the Mozilla support articles where this info is stored, but my backups have no Firefox folder under "Applications Support." Did it get eliminated when I signed up with Mozilla in order to get help with this? These files are on my current system, but they only have a few items that I've entered today.

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

Version 118.0 Seit heute Morgen kann ich Firefox nicht mehr normal starten. Nur als Admin, es werden aber keine Webseiten mehr angezeigt und wenn ich in die Adresszeile etwas eingebe passiert nichts. Ich habe den Browser deinstalliert und neu installiert, ohne Erfolg. Dann habe ich die Unser Datei gelöscht, ohne Erfolg. Die Firewall blockiert nicht und den Virenschutz habe ich deaktiviert, ohne Erfolg. Beides ist das original Win10 Werkzeug. Wenn ich about:support eingebe passiert nichts, kann das Menu aber über den Link öffnen

Using Firefox 17.0.1 on MacOS Ventura 13.6 on my 2017 iMac I am unable to connect to the internet while using Private Internet Access (PIA) VPN. All was working normally until I installed MacOS Ventura 13.6 yesterday. The VPN works normally when using Chrome or Safari. I have tried changing my network proxy setting without any luck. The default setting is "Use System Settings", using No Proxy or Auto Detect Proxy doesn't help. I don't see a switch for Enable DNS over HTTPS. All works fine when the VPN is disabled. I tried deleting the VPN a couple of times then reinstalling but that didn't help.

What am I missing here? I have used this VPN for years without any issues & it worked on Firefox until I installed MacOS 13.6...... using 13.5 I had no problems. Any suggestions or thoughts would be appreciated.

Thanks...... Brad

In Google Docs, my text cursor will randomly bounce backwards on the page if I perform certain actions, such as pressing Tab in a bullet point list to create a subitem, setting the text to italic, or sometimes just clicking the cursor to the end of a document. Sometimes reaching the end of the line is enough to make the cursor jump back to a random position on the line.

I have tried this in a new profile with no addons and the problem persisted. I could not confirm this in Chromium last I tried. (But I swear I remember it happening in Chromium once or twice before) I have confirmed it on my PopOS laptop and my main PC booted into both Linux Mint and Windows 10.

I am running Firefox version 116.0.3 (64-bit).

Hi. Is there a way to customize the order of Firefox headers and footers on printed pages (including print-to-pdf)?

I prefer the header to be url only, in the center. While the footer has page on left; title in the center, and date on the right.

This used to be easy to accomplish with print options in older versions, then -- as the print dialog changed (and actually improved a lot in most *other* ways) I had to turn to about:config modifications like those described in the 1/27/21 reply here: https://support.mozilla.org/en-US/questions/1323433. But now I can't seem to find any way to have any control over print headers besides "on" and "off."

One problem I find with having both page title and url on top is that these can be long, causing one or both to be truncated.

I'm using Firefox 115.3esr.

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Firefox tabs keep crashing repeatedly and sporadically. I had the most recent version on my mac. I have a MacBook Pro (13-inch, Mid 2012) I restarted Firefox various times, restarted the computer, tried troublehsooting mode, uninstalled Firefox and installed 115.2.1esr . Problem continues even in troubleshooting mode.
