When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

I have been experiencing a problem with Cloudflare specifically on one site (character.ai) and when the verify you are human pops up. It takes me in a seemingly infinite loop. On the Cloudflare community site they say it could be because of things like adblock but even without any adblock or anything of the sort on it does the same thing. Sadly Cloudflare community doesn't support being used on Firefox. So maybe they don't support being used on Firefox in general? I have contacted the actual websites support but they don't seem to even read submitted inquiries because I never hear anything back from them except the automated message they received it. It is now preventing me from using certain things in general which as before it wasn't that big of a deal but recently they changed the site layout and still allowed you to use the old layout but the verification blocks you from using the old layout. The first one is one from a couple of weeks ago when it only effected me trying to open things in a separate tab and the second one is the newer one which prevents me from accessing the old layout. I'm not sure what to do about it since nothing I specifically could do to solve it has helped. I have opted into sharing data under troubleshooting IDK how well that'll help.

Hello,

I have tried to download the newest VDH Companion App (via the link on the github.com webpage) Seven (yes, 7) times and every time the download Fails or I get "Zero bytes". I tried to contact "Support" but there is only a Support Forum and nobody else has posted this as an issue that I was able to find when I searched. So no support is offered. The website suggests that I create an account to be able to post a new issue. However, Every time I have tried to set up a github.com account, I am Unable to do so. The page to set up an account either doesn't load OR if it loads, I can not add any information to it. I am a VDH Registered User and until this morning, the current VDH app I am using, version 8.2.1.1 was working just fine. But now when I try to use it, it says that my VDH Companion App needs to be updated. But I can not even download it to update it. I am running the current version of FF, 123.0.1 on an iMac with Sonoma OS 14.4. We used to be able to email Mig but not anymore. The github.com support page is unwieldy at best and I see that numerous requests for help or support have not been answered or even acknowledged. I am a paid Registered user with a license, but that doesn't seem to matter. I, like many others from what I read online, count on using this app almost every day and I would think that the mechanism for updates should be working correctly. The update files I tried to download came across at crazy low speeds, like 20.1 to 40.5 Kbps! I spent over an hour with Tech Support for HughesNet and much to my chagrin, No Other Websites had any issues with download speed. It was only happening on the github.com website and this one file update. Sorry if TMI but I am just trying to thorough.

When in Google Sheets in Firefox a single scroll click of the mousewheel takes me to the very bottom right of the sheet. The scroll wheel is then disabled vertically and horizontally.

Error is verified for all Google Sheets. Problem does not exist when accessing these sheets in Incognito Mode.

Error does not occur when accessing these sheets in Chrome.

Sheets is all but unusable without mouse scrolling capability.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

I just recently had Firefox updated, and I'm already having problems regarding notifications. When a notification starts up while I'm typing, it takes me out of it and I have to click back in. I had to turn them off temporarily to avoid flow breaking. This never ever happened before the update as the notifs worked perfectly fine w/ no interrupting. I also noticed in the taskbar, each notification is treated like a new browser window for some reason. This may be related to my current issue.

Hi, my bookmarks toolbar doesn’t show when I launch Firefox. They always use to. When I click on View>Toolbar>Bookmarks Toolbar>Always Show - the Bar shows. When I click on any bookmark the bar disappears. If (in new window) I click on View>Toolbar>Bookmarks Toolbar>Always Show - the bar appears, when I then open new tab it does not show on new tab and when I click back to previous tab bookmarks are gone.

I have restarted W10 PC, no change.

Hope you can help, many thanks, David

Yesterday, I ran a format on my computer with Firefox in installed on it. When I tried to recover my settings, history and bookmarks later using sync after logging in to my account nothing happened. Can you please help me recover my data? Thanks in advance.

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

I want to uninstall and maybe re-install some add-ons. But when I goto the add-on page. It just appears blank. So are some other pages in the support/ help sections. Another most notably, is (via menu) help -> more troubleshooting information. It just sends me to a blank page! See the uploaded images for the pages I get send to.

Help please with changing my add-ons

When typing if I make a mistake I'll usually just delete the entire word and retype it rather than fix the spelling but to do that I need to use CTRL. Now when I press CTRL it zooms in the page even though there are no other buttons being pressed.

I have just upgraded to Firefox version 123. Now whenever I start Firefox on any of my profiles, it will immediately or almost immediately display a "Welcome back" popup stating that "Here’s a quick reminder that you can keep your favorite indie browser just one click away." and provides a button to make the browser the default one. That's exceedingly annoying - I can understand that Firefox wants to notify my once in a while, but this happens at least once a day, probably more often than that. I looked over the source code and got that it is a "spotlight" feature, but I failed to find any settings that would turn it off. Any idea how can I disable this forever?

My Firefox has gotten so buggy lately I can't use it. I'm writing from Edge. THere are numerous issues. The sign in process got messed up a couple months ago. IT asks for email address, then doesn't provide password screen option, takes forever to send email, and then sometimes repeats itself. Tabs crash and clicks fail to work randomly. Out of desperation I reset my Firefox password and that seemed to help temporarily, but not enough. So what's happened and how to fix??? Thanks.

This issue has arisen on Firefox for Linux Mint (my current version is 123.0 (64bit)). I like Firefox, and I like its bookmarks toolbar, and have used it for many years, but there seems to be a new bug introduced today:- The bookmarks toolbar is present and correct when I start Firefox, but now it disappears as soon as I select any bookmark, or if I enter any web address or if I open a new tab. The [View >Toolbars > Bookmarks Toolbar > Alway Show] option is already selected, but the toolbar is no longer visible. If I click on it again, the bookmarks toolbar reappears (or I can restart Firefox, and this will also restore the toolbar). But the toolbar now disappears as soon as I use the browser in any way, and so is currently not really of practical use, as it needs constant restoring. Hope you can help resolve this. Many thanks in advance
