Firefox Community Forum

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

Sometimes when I do a google search the results come up in a foreign language! I am in the USA and speak only english. Changing my preferences doesn't always maintain the fix.

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.

The Russian language is not listed in the "To" part when I want to translate a page. Although it IS listed if the page is in Russian, so it suggests to translate from Russian to some other language. The language is installed in settings.

I have this message after returning from nightly version to the stable one: ``` Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox. ```

As per the topic title. I would like pages to always automatically translate from english to my chosen language. However, when I select the option in the context menu, then revisit the setting, the check box remains unchecked. This remains the case on multiple tested operating systems, Arch Linux and Linux Mint. Thank you in advance.

Hi people,

I have used Firefox for years but after the latest Microsoft Update it no longer starts or runs. Another product, Libre Office, also failed at the same time and I have been unable to resolve that problem either.

I have uninstalled Firefox, downloaded a fresh copy from the Mozilla website and reinstalled it a couple of times but when I click the desktop shortcut nothing happens. I can right click the shortcut and select the "run as administrator" command and something like the Firefox browser opens but all my shortcuts are out of date on it and the browser will not access anything on the net.

I also use Mozilla Thunderbird as my email providor and that is still functioning normally.

Is this some monkey business from Microsoft, a fault in Firefox or a fault somewhere in the inner workings of my computer?

Kindest regards, Colin Ballard, 23 January 2025

Hello,

I have encountered an issue on some websites where the Japanese text is using the font "Microsoft YaHei" when it should be using "Meiryo." Some examples are on the website bluesky, and bold text on Twitter such as in usernames.

I originally thought it was an issue on my end or in Windows, but when checking other programs and websites such as dengekionline and the non-bold text on Twitter it is using the correct font which I have confirmed via the inspector under the font section. When starting Firefox in safe mode it seems to use the correct font on the previously mentioned websites, so I disabled all my extensions and themes and this did not resolve the issue. I did a Firefox Refresh and this also did not resolve the issue.

I am not familiar with the intricacies on the Firefox about:config to really delve into the exact cause, so I ended up just reverting back to Firefox 134. On Firefox 134 with my same extensions previously the font is now back to Meiryo as it should be which leads me to believe it is something that was changed in Firefox 135. One thing I am considering is that the Japanese text is being recognized as Simplified Chinese by Firefox 135 as Simplified Chinese uses the Microsoft YaHei font as a default.

I have attached some photos that shows my Japanese font settings, and the same post by a user one on Firefox 135 which is using Microsoft YaHei and another on Firefox 134 which is using the correct Meiryo. I have also tried disabling the "Allow pages to choose their own fonts, instead of your selections above" and then restarting on 135, but this did not resolve the issue. Thank you for your consideration.
