Firefox Support Forum

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

I have:

125.0 (64-bit) Mozilla Firefox for Ubuntu canonical - 1.0

Video on Facebook plays without sound. The video plays, I see the image normally, but no sound. Video on Youtube works perfectly.

Fresh install without addons or plugins. Switching to "Troubleshoot mode" does not change anything. Youtube with sound, Facebook without sound.

Any ideas where to look?

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

Hi - I can't get 'pocket recommends' stories to appear in FF on my macbookpro (14.4.1)

I've done pretty much everything I can find online including the below – nothing works

ANy ideas?

Type "about:config" in the address bar and press Enter Click "I accept the risk!" to proceed In the search bar, type "browser.newtabpage.activity-stream.feeds.topsites" and press Enter Right-click on the "browser.newtabpage.activity-stream.feeds.topsites" preference and select "Reset" Restart Firefox and open a new tab to see if the Pocket Discover tiles appear.

been getting a printing error the last couple days this message "error occurred while printing". Printer then puts out partial page(s) then stops printing. been trying to print copies of tax forms ( 11 pages)?? page that print shows Firefox in top left corner of page. Today same problem with a four page email print job.

We have used Firefox for access to certain sites for years. Recently, we wanted access to particular sites, but the info boxes needed would now not allow entries. Then, we went to Chrome and there was no problem entering the info. Please provide a response to resolve these issues of Firefox not allowing data entry, but Chrome allowing data entry for the same sites.

Hello, have been scratching my head for a while on this one. Have a freshly setup install of Debian 12, using Sway (wayland) as my Window Manager. I am really struggling with slowness in Firefox, page loads take easily 15 seconds whereas loading the exact same page in another window at the same time with Chromium Debian build has near instantaneous load times. I've tried the following troubleshooting steps: - Created a new firefox profile - Tried "Troubleshooting Mode" in Firefox - Disabled ipv6 in firefox about:config and in Debian - Tried different DNS servers - Tried different non-debian specific builds of Firefox - Tried Firefox Beta and Firefox Nightly for Debian

None of these steps made any difference, and Chromium has continued to be significantly faster. Am really stuck here and would love to get to the bottom of this as Firefox is the only browser that works with a HiDPI display in Sway without blurryness. Happy to provide any and all diagnostics and reports that are needed. Thanks in advance!

EDIT: It seems to be some kind of networking issue, using a VPN solves it. But still doesn't explain why Chromium would behave differently.

I just got a new computer and had my info transferred. It is probably the latest version of Firefox on the new computer now. On the previous version it seems like Favorites was spelled out toward the top of the page on the left hand side. I see now it is just a star icon. Is there any way to get it the way it used to be? I'm sure I will get used to it the new way, but I still liked it the other way. Thanks

With the update to 115.10.0esr my bookmarks that were on the left hand side of the screen are gone. When I look at bookmarks there are a few, but I had multiple folders for different subjects, I do not find. I would like to have the procedure to return my bookmarks back to the left hand side of the screen with all of my bookmarks, bookmark folders, and other bookmarks like it was prior to the update. Thank you for help, Steve Zimmerman

Had to replace FF with Chrome in order to play DRM content on my W11 laptop. I get message saying you are downloading remedy, but nothing ever changes. Would prefer to continue 15+ year relationship with FF, but seems like youre abandoning capabilities for DRM video content?

I have to put my face within inches of the screen and strain to see the text in Firefox browser menus, tabs, and search bars. How do I adjust the font size?

I'm not a programmer. If I need to enter code please be pedantic about descriptions of how to do that.

Once updated Firefox all old tabs didn't open ( and it was not possible to restore them anymore). So I'd like to restore all old tabs of yesterday session. Really important for my work. Looking forward to hearing from you asap. Regards, Orlando.

Currently, I use Firefox version: 116.0.2 on Ubuntu 20.04.6 LTS.

I encountered a phenomenon like this:

• When I logged in to the application, in the tab I was working on, the Firefox session memory was lost (don't open new tabs)

What is the cause of this phenomenon? How can I fix it?

My Firefox recently updated to version 124.0.2. Afterwards my taskbar shortcut broke, so I pinned a new one manually (right-clicked Firefox in start menu > open file location.) When I opened Firefox it had reset the primary profile to be default, so I changed it back to my BetterFox profile. Since then I've run into several oddities, such as Firefox crashing when it's running in the background, getting an error saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window," when I try to open it, invisible shortcuts in my taskbar(see image) and my bookmark visibility resetting from always to only in new tab every time I start up Firefox. Please help me.

Hello,

 One of my email accounts Yahoo or Gmail appears to have been hacked. I received two phishing emails this week --3 if you count the last one who said she was calling on behalf of Medicare/Social Security and All members could get a preloaded card for several hundred dollars. I knew there was a plan to help certain folks, but it was not available to everybody. I asked her for the name of the plan and she hung up. the webpage she sent me to first or told me to go there where I could talk to a licensed agent. Do people who answer the phone have a license like insurance salespeople? Anyway, they had copied the govt. the site is right up the US sea.

Okay, just an example so I decided to try that KeeopassXC program you were offering but I could never get it to complete.

but it did something as I can't use my password They cancel your account if you tell them the truth --better just to say I need help resetting my password. They then ask you to send them a picture ID as in Driver's License. Noway I am going to do this --so I have at least some pretty valuable info if I can't get in.

Ny first time writing here - if any response please direct suggestions to pke225x2gmail or I guess I will check here. Don't know how you put people with possible solutions to seeker of HELP.

Sincere Thanks Paul

Hail all:

OS: W11Ent_x64 V: 22h2 (b: 22621.3447) FF: 124.0.2 x_64 I tried several "Group Tabs" add-ons, like: Simple Tab Groups. Tab Group. And I few I can't even recall the name from. Yet, none works. Not ONE.

Now, I use Edge as well, on my corporate system that I got from work. Personal PC I use FF on.

But, the Edge Tab Grouping, which allows tabs to be "put to Eco-Sleep", while hidden the open tabs by clicking the Group-Tab Icon, is a feature I sorely miss in Firefox.

Odd, as, so many requested this feature, how come it has not been implemented over the many years of people asking?

Either way: Does anyone know a good, WORKING add-on that does the "Edge Thing" with FF tabs, please? Since, I often got like 200 tabs open, which is a real misery without Tab Grouping and "Hiding".

Thank you aforehand: Ke'Ylan.

Prior to about a month ago, downloading worked as expected: - click a link - the save to... dialog opened - choose the folder - the download is off and running

No more. For about the past month - click a link - wait for a long time with FF frozen - the a wheel starts rotating - after a full minute (or more) the save dialog appears.

Something has been broken in the mad-dash to push updates. It's fine for browsing, but the, you need to download. At that point you wish you were using a different browser (any other browser, in fact) since FF is the only oe that has this problem. Downloading works fine in a 8 chromium browsers that I have and in the 5 FF clones (like Waterfox)

It's just FF that's broken. I can no longer afford to set it as default because of this. The others are not perfect (WF won't activate Pocket, foe example) but downloading promptly is critical.
