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 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

I want to disable notifications when a download is finished, however the key in about:config 'browser.download.manager.showAlertOnComplete' does not exist any more. Is there some other way to disable these notifications?

A couple of weeks ago I migrated from Edge to Firefox. I exported and imported my bookmarks. All was good. Suddenly this morning, my bookmarks are inoperative. The folder structure is there, containing entries that appear to be my bookmarks. If I left-click on one, nothing happens. If I right-click on one and choose Edit Bookmark, the fields in the dialogue are all empty.

When using private browsing window, bookmarks toolbar keeps disappearing every time I open a new tab or anything else. My setting for show bookmarks is "always show" and it works normally in a regular window. It also used to work normally in private browsing until a few days ago. Clicking "show bookmarks toolbar" works until I open any of the bookmarks, then the toolbar disappears again. How do I make the toolbar permanently visible in a private browsing window?

Hi.

Ever since I upgraded to version 123.0.1, I am constantly getting slowness on websites stuck in "Performing a TLS handshake..." Eventually the websites load, but it's frustrating. I have read about the various solutions and have tried the following: Disabled IPV6 Refreshed Firefox Reloaded Firefox Disabled and removed all extensions Restart in safe mode Create new profile

This was not happening in version 122 and before. Microsoft Edge does not have this problem, but I prefer to use Firefox. I am running Windows 11 Pro. Any ideas?

Thanks

Above 70-75k characters, text input fields on any site have a ton of input lag -- like, I have to wait 10s after I type a sentence for the sentence to finish slowly updating letter by letter. I've tested across multiple sites, and in Private mode (to confirm it's not caused by extensions, none of which are allowed in Private mode).

I also tried setting `accessibility.force_disabled=1` as suggested here and here, but that didn't help (and yes, I restarted). Disabling hardware acceleration didn't help either.

I've just tried to save something from firefox on linux(Manjaro KDE) and was baffled that there doesn't seem to be a way to manually enter the path and navigate to it in the save dialog. In addition to that, there are many locations missing and I can't seem to find a way to add new custom or favorites ones either.

All that combined means it was impossible to save my file directly to a network location, which is something I very often need to do. It just seems insane for such a basic feature to be missing and I've found a 4 years old thread about it meaning nothing has been done to fix this since? https://support.mozilla.org/en-US/questions/1279125

The only way I can see would be to mount the network path(not a good solution for one offs) and navigate to it(a symlink can make it closer to one of the existing shortcut but still annoyingly require more clicks) every time but that's very tedious since most of my saving is on a specific server drive.

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.

On my computer Firefox ask for the master password every time at startup. On other computers in my family, Firefox only ask for the Master Password when accessing a site with a password. I tried : - to disable than reenable Master Password - start in SafeMode without success. How can I solve my issue ? Thanks in advance for your help

I've read all the suggestions but can't get Firefox Sync to transfer the open tabs from my old PC to my new one. I'm signed in on both to the same account, both are on my LAN with a wired ethernet connection, and I've checked every box in the "what to sync" field. When I click "Sync Now" the icon spins for a few seconds like it's doing something but the tabs from the old machine do not appear on the new one as I expected them to. Nor can I get them by closing and doing a Restore Session.

This seems pretty straightforward and how most users would expect it to work - am I missing something? If not, why isn't it working?

I'm not very good at English, so I use a translator. After updating to the latest version of Firefox, the problem I'm having is that when I play a YouTube video on the web side, the playback box will have a large white colour, as shown in the red box below. I would like to know what is causing this, my current version is 123.0

When launching Firefox Malwarebytes reports a trojan and shows blocked website verifications.io This happens just about every time. Wikipedia tells me "Verifications.io is a defunct email-focused technology firm whose primary practice was to validate email addresses for email marketing platforms. The company's platform allowed for email marketing firms to submit lists to the company, which would verify the lists for valid email addresses."

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.

Hello,

I install language pack from https://addons.mozilla.org/en-US/firefox/language-tools/ https://addons.mozilla.org/en-US/firefox/addon/russian-ru-language-pack/

But there is still no sub-menu item in the menu

Ubuntu 22.04.3 LTS Firefox 123.0 (64-bit)

The browser deletes cookies when closed. Every time I log in, I need to re-enter passwords (they are saved) on all sites, this is certainly tiring. I read about a similar problem from other users, they had the “Delete cookies and site data when Firefox is closed” setting enabled, but I didn’t.

I use the numerical keypad frequently and need to use "/" often, but that key shares the shortcut for "quick find" which I then have to exit and click back into whatever text box I was typing in before I can continue. The alternative is to continually move my hand back and forth to the other "/" shared with "?". Both are annoying and unnecessarily take extra time.

I would very much like to disable the keyboard shortcut attached to the "/" key on the numerical keypad.

Thank you!

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

Howard
