Firefox Community Forum

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Two issues using latest version of Firefox with Windows 10.

These 2 issues have occurred in the last few days

First I cannot attach my files to my emails using Gmail. I'm able to do this using Edge or Chrome

Second, normally when I used to start typing the name of my correspondent it would automatically complete. This is no longer working. I'm able to do this using Edge or Chrome

the attached printscreen shows both issues

every time i clear cache and history this is what i see in words with frind not it has not always done that seems ince the nest Firefox update it does it I hav eanother problem when shut dw nte computer and restart Mozlla hangs and will not load could it be my home page I use xfinity

 whay doe it   hang and take forever to  load  at start up

Firefox 102.0.1 (64bit), Linux, Sway (Wayland), MOZ_DBUS_REMOTE=1, MOZ_ENALBE_WAYLAND=1 When I hover over a menu item, the hint shows up and the menu disappears visually, it is still there, as I can interact with it (mouse click or enter).

On chrome I have several profiles and different ones use different LastPass (and other) extension services. EVERY PROFILE maintains it's OWN login information.

Firefox, however, does NOT ISOLATE PROFILES. On ANY Firefox profile, if I log into LastPass EVERY PROFILE is forced to use THAT information- even going as far as logging out and logging into the OTHER profile's information/account. This is 1990's level idiotic.

WHY are profiles SHARING LOGIN INFORMATION!? This is entirely stupid and defeats the entire purpose of multiple profiles.

I had this happen with Facebook logins, too... WHY does ONE profile FORCE OTHER profiles to change their login information?! WHY ARE THEY NOT SEPARATED?!

How do I solve this?!

it is the SINGLE biggest reason why I can NOT switch to Firefox again. Chrome does this. Chromium does it. EVERY Chromium browser does this. 10 years ago Firefox did this... and I left it when it QUIT doing this... when it BROKE profile separation.

Why is this STILL a problem?!

What Happened To The PASTE Option, When You Are Composing A New Email In Outlook  ?

If You Copy Something, Then Right Click In The Message Section Of The Email, You Do Not Get The Drop Down Menu With PASTE As An Option.

You Only Get The PASTE Option When You Right Click Into The SUBJECT Line.

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

After switching to Firefox version 123, I encountered an error on our website: '1,000,000.00 is not a valid number.' It seems to be a form validation error, but it worked fine with previous versions of Firefox. The application is built using GWT (Google Web Toolkit). Any help would be appreciated. Thanks.

I wondered several times why firefox recovers old tabs when it chrashed. now i see that in my profile folder/sessionstore-backups the file recovery.jsonlz4 is some days old (while i was using firefox in the meantime very often) and does not update frequently as requested by about:config browser.sessionstore.interval = 15000 (15s). - this folder or the files are not locked. i can delete/rename them, they are not re-created - there is no file sessionstore.* in the main folder of firefox profile while running firefox - i am using 102.4.0esr (32-Bit) on a company PC (could there be any restrictions?) - the file previous.jsonlz4 seems to be created correctly when firefox is closed normal (which is not my usecase, i want to restore up to date tabs after crashes) - i am not using a private window

do you have any idea?

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

I am using a Samsung Chromebook Pro V2, running Debian, and installed Firefox using the Flatpak command "flatpak install flathub org.mozilla.firefox". The Firefox icon appears in the Linux apps group and I have opened Firefox using that icon.

How do I get links in my Linux apps to open Firefox and take me to the URL?

Thank you and Happy New Year, Abe

I've been with yellow folders for several years. In the version that I have now, version 111, no longer works. I was put at userchrome.css the following: @namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); .bookmark-item[container], treechildren::-moz-tree-image(container) { fill: gold !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksToolbar) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_BookmarksMenu) { fill: black !important; } treechildren::-moz-tree-image(container, OrganizerQuery_UnfiledBookmarks) { fill: black !important; } treechildren::-moz-tree-image(container, livemark) { fill: orange !important; } .bookmark-item[container][query], treechildren::-moz-tree-image(container, query) { fill: dimgray !important; }

I do not know because it doesn't work now. Maybe version 111 no longer admits it? Do you know how to put the yellow folders?

When I try to go to my webmail I sometimes am presented with a Deceptive Site Ahead warning.

I am quite happy that although the SSL might not be current that the website is safe for me to go there. How do I stop this annoying feature from activating?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Hi everyone,

lately I started experiencing a font-family-related issue. On certain websites the font-families/styles look broken. I tried troubleshooting the issue by myself without any luck. What I did so far was reset my Windows fonts to default, reinstall Firefox and look what font-families are loaded through the Inspect tool. If I opened the same web page in Chrome the font looks OK. Two websites the issue is most visible at - support.fiverr.com and gmail.com when someone replies to my e-mail.

Please find below a screenshot of what I mean

I recently migrated from Chrome to Firefox on my Mac and successfully imported all data, bookmarks etc. However I cannot figure out how to ADD a new bookmark to an existing folder. Every page I read about bookmarking fails to show how this is done. In Chrome its simple since the drop down menu allows the user to view every folder, but in Firefox I don't see how to do this. Furthermore, when I go to Bookmarks>Manage bookmarks I don't see any of my folders..PLEASE show me an EASY way to do this. Thank you

Something is going on with Firefox. Web pages will not load, and the error message is "we could not verify the certificate: reason = timeout".

My internet speed is 400Mbps. I don't have a delay here. I've rebooted the PC, restarted Firefox, and about 3 out of every 5 web pages comes up with this error.

I couldn't even get to the Mozilla support site with Firefox. I had to use a different browser.

What's going on?

I run a simple website. gcessa.org. Until recently I was able to import a .doc or .docx document converted to a text document into the site and it loaded like one would expect. Lately the characters ', ", and - have been resolving as a �. There might be others I'm not aware of. Which means the characters are not found in the codex. What do I need to do to resolve this issue. I believe it started after one of the last two updates. I don't see this happening in edge or chrome.

Thanx
