After updating to 114.0.1 the print orientation for pdf's has disappeared. PDF's we used to print often now come out with the wrong orientation and have to be printed with the system dialog instead.

Tell me how to "re" install my previous version of 113.02 and then fix this bug. Don't know where to get "old" versions to download and will old version just "install" right over the version installed and keep all the bookmarks, etc.?

I am using Arlo security cameras which store the video captures as MP4 files. The Arlo app has video playback feature that works in Chrome or Edge but does not work in FireFox. From what I have been abe to glean from searches, Arlo uses HEVC Codec that FireFox either isn't compatible with or is lacking the codec. Any suggestions?

After the Firefox update to 114.0.2 on my WIndows 10 desktop computer, the display of the Google Voice website became all garbled and vertical scrolling stopped working, making it impossible to read new next messages. My laptop, which has been turned off and has not taken the update, is still running the previous version and does not have the problem. I'm wondering if others have had the same issue.

I recently noticed that in the settings it says "Your browser is being managed by your organisation". The certificate "ImportEnterpriseRoots" seems to be affected. I have seen guides saying to delete a registry key but I do not have a Mozilla folder in my policies.

It is worth noting I do run two anti virus software. Kaspersky total security and gridinsoft anti malware. Just wondering if there is a way to permanently remove this or if its just a side affect of my anti virus software.

Thanks

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

My Ledger is having a problem linking to MetaMask in Firefox. This happened to me a couple months ago and I followed the steps in the MetaMask support article about this very problem. I got it to work right away at that time by going to "about:config" and setting u2f to "true." I followed those same instructions again today to no success. I also updated to the current firmware on my Ledger device. I've restarted Firefox, my Ledger, and my computer in every order I can think of and nothing has changed. I've changed u2f to "false" then restarted and then back to "true" and restarted and nothing changed. I'm out of things to try so I'm messaging in hopes of finding a solution. Thanks.

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.

When I click a mailto link it brings up the GMail app. Instead I want the Yahoo Compose window. Several posts suggest various arcane methods. Either they do not apply or they require hacking. Has the situation improved?

How can I make mailto links go to the Compose window on mail.yahoo.com?

I see this issue posted in other questions but none of the solutions given works. For one, the click on items you talk about don't exist, like the "Firefox Options and/or Preference" is no where to be found, top left click on Firefox Icon or top right bars. The right click button does not work in your browser at all. I don't have this issue on my work computer or my work laptop and they are running the same version, 1140.1. I am use to: Right clicking Firefox icon in tool bar and a menu coming up that allows for several choices. Right clicking in the top bar with page tabs and being able to put the bookmark menu bar up permanently (the main reason I use Firefox, ease of accessing bookmarks which Chrome and IE make ridiculously difficult}. How do I get functionality of my right click back?

Hello, I have two websites that I've designed with cursive fonts in some headers. Whereas they display in other browsers, they do not display in Firefox. I asked this question years ago, and to date, no one has provided an answer.

Not only do the headers not display the cursive font: savoye let and allura, what they show are enlarged and bold letters that completely destroy the design. Surely, there is a reason for this.

Here is one of the sites (the other is still in design mode): https://summitlighthousephoenix.org

This is a duplicate question because it was not solved the last time, and there were no other replies.

1. Works on all other browsers, but Firefox plays only audio and a blurry video (see screenshot). 2. PC is equipped with a beefy i9-13700 and RTX 4080; even with that CPU, disabling hardware acceleration eats up almost 25-30% CPU and it is not practical to watch videos that way. 3. Is this bug really not that common? Is it just me and that's why there's no traction for fixing this bug? 4. How do I elevate this request so someone takes action, in case we find no solution in this thread?

Youtube, sometimes, loads for ~5-10 seconds on average for no reason, doesn't load the video or audio at all. Extremely frustrating when I'm just browsing, it may not seem like a long amount of time but I shouldn't have these issues to begin with. Cleared cache, no addons are out of date or tamper with Youtube. Tried every fix I could find on the matter, nothing seems to have worked. Issue persists. I had similar issues with Kaspersky AV installed, so I had just uninstalled it. Prior to this newest firefox update, I have had no issues at all.

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 installed what I thought was the "trust wallet" extension. It's not the real trust wallet. I had a little over $5K stolen in BTC, ETH, and SOL. Is there any way you can help me catch the individuals or somehow get back my stolen funds? Or any advice or direction will be helpful.
