Some fonts randomly use an ugly, blocky font for no reason. I've seen it happen on some web pages and PDFs but not on all. I have tried other browsers but it is a Firefox-only problem. It doesn't occur in troubleshooting mode as shown in the attached picture. Any help to resolve this would be greatly appreciated!

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

With the last update I suddenly have the url/search box background and its search results drop down background set to an ugly pink with diagonal lines.

I am visually impaired and now its almost impossible to use firefox because I can't read the text on top of the diagonal colored bands. There doesn't seem to be any settings to turn on or off this appearance.

I will have to switch browsers until this is fixed and I don't want to.

Related to some personal SVG project files. Which are relative large files (containing lots of generated paths and other data).

On the largest of these files I spotted that some general svg-viewer failed with a "XML parse error: cannot load more than 200.000 XML elements" error message.

The same file, when viewed in Firefox (114~, Linux, Mint), also developed some odd hiccup that did not make sense. Unless ...

Is there a similar limitation active in Firefox ?

- I tried to see if "Inspect>Console" gave some potential related message on this. But spotted nothing out of the ordinary. - Searched developer.mozilla.org for any related svg data. But could not find any. - After ditching some data in the effected file, unrelated to the hiccup part, the hiccup disappeared. Suggesting I did hit some svg limit in Firefox. - File size: ~26.5MB. Number of elements: Other than more than 200.000, unknown at this point. (not sure how to count them at this moment either)

Hello and thank you all in advance for giving your time to help us!

I run Firefox 114.0.1 on an Apple Mac Mini running Monterey 12.6.6.

Under the "Other Bookmarks" heading in the Library, I keep quite a lot of folders dividing my bookmarks into the various subjects they relate to and some of those folders are subdivided into subfolders.

One of my "simple" folders is called "PENDING" where i store stuff to look at when I have time. Last week I noticed that folder was missing! There's no other explanation than I stupidly deleted it without knowing, and it contained a lot of stuff!

I read up on restoring bookmarks from backup but

a) I only need this one folder and b) I don't want to overwrite all the bookmarks I've added in the past weeks.

Even if I could get the bookmarks from that one folder in a plain text file that I could read, I've no problem doing a bit of work, pasting each one into Google and re-acquiring it as a bookmark.

Any advice will be deeply appreciated!

Many thanks and very kind wishes,

Jim

When using custom search engines:

In the search bar, all you have to do is click once on the engine icon and it searches. In the URL bar you have to select the search engine icon and then click "search with".

Is there a way to eliminate the second click in the URL bar?

Thanks.

Windows 10, Firefox 114.0.1

Hello, I wanted to restore Firefox to start clean. I wanted anyway to reinstall my (few) extensions, all of which are safe and well known. When I do that, though, their icons don't show up in the toolbar. When I open the "customize toolbar" setting, extension icons aren't there. So there's no way to add them to toolbar.

I tried all possible methods: - "Restore Firefox" and resync my account (extensions are reinstalled but icons not shown in toolbar / customize toolbar) - "Restore Firefox", not syncing, and manually installing extensions (icons still not shown in toolbar / customize toolbar) - Uninstall Firefox, delete everything in Profiles folder, reinstall Firefox. Same behavior.

So, it seems it's something not related to a broken profile, since a fresh profile, with no syncing, does not fix the issue.

Any clue of what I could try? Thanks!

Lately for the last 3ish days my YouTube connection speed on Firefox and only Firefox has been terribly slow. So slow that it can't even watch normal HD content. But not always, sometimes it does work at normal internet speeds which is so weird. I have around 500 Mbps download speed internet so I know it's not the issue. The picture with the slow download speed is on Firefox and the fast/normal download speed is on Chrome. Sometimes in a private window Firefox runs at normal speed but not always, I don't think it's an extension issue.

Hello, Microsoft Defender did a scan tonight and apparently detected a trojan script, located in the folders for Firefox extensions for both profiles I use on my computer

Trojan description: Trojan:Script/Wacatac.B!ml

Files: C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[default profile]\extensions\langpack-fr@firefox.mozilla.org.xpi C:\Users\[user]\AppData\Roaming\Mozilla\Firefox\Profiles\[second profile]\extensions\langpack-fr@firefox.mozilla.org.xpi

This scan happened at 9pm, and a previous scan at 6pm didn't show anything. When it detected the script, MS Defender contained it and apparently deleted it when it asked me to restart the computer, I then did a full offline scan and nothing else showed up, same with a full scan with the free version of Malwarebytes. I didn't do anything unusual between 6pm and 9pm, so I'd like to know if there's a way to determine whether that script was an actual threat (instead of a false alarm)? If so, any way to know how long it has been on my computer? Any further risks to take into consideration? Other steps to follow? Thanks for the help

Firefox 114. Fedora 38 with Gnome 44.2. All video playback is shaky except in YouTube. MSNBC, CNN, Instagram, Twitter, and ESPN video is shaky. Tried disabling all add-ons and no help. Any ideas? Thanks in advance. Bob.

To resolve an issue that has been plaguing me, I did a clean install of Firefox. I followed some instructions I found on here that ensured that all I had to do was rename the existing Firefox folder to something else, download and run the installer again, and I should have done a clean install without losing my user data.

The issue I had has been fixed, but all of my add-ons and bookmarks are gone. I can get the add-ons back, but where can I find the bookmarks in the old Firefox folder?

I have bought a new pc with Windows 11 home pre-installed and set Mozilla Firefox latest version as default browser ...the issue i am having is placing add-on extension shortcut icons on toolbar. I installed Norton Safe Web and this installed ok and is listed in extension control panel and when i click puzzle icon Norton Safe Web is not shown under manage shortcuts nor can i see option to Pin to Toolbar. Have tried several attempts but still get nowhere.I uninstalled Mozilla Firefox...restarted pc ... did a fresh install of Mozilla Firefox without altering any settings..re-installed Norton Safe Web and still cannot see option to Pin to Toolbar.Clicking the gear icon does not help Have i missed a step somewhere ?

After the latest update, "synced tabs" suddenly appeared in my history menu above Recently Closed Tabs. I don't use syncing of any sort so this is just a nuisance. How can I get rid of it?

Recently started to get this popup - see attachment - and I don't know why.

Please advise a remedy.
