Where is a link, icon, or ANY WAY to add a shortcut site to my Ubuntu FF **DESKTOP** homescreen?

I already have 4 rows (since 2013 over many Linux laptops. Ubuntu, Mint, popOS, and now Ubuntu 26.04 LTS).

There is room in the fourth row for a few more. BUT I don't see any icon or link or right-click option to add another!

Phrasing the article search various ways gets me a lot of unrelated stuff.

EVERY help article, of which there are few, seems to have a BIG-ASSumption that everyone is using mobile Firefox.

NO! NO three dots. No right click brings up anything. NOTHING in settings. I've been through everything in the 3-bar menu, and there is NOTHING. (I already use it to sync, go to OTHER settings, go to help, etc.)

This is a day after an update, though I don't know how that affects it.

Usually if I forget how I did something, I just explore and find it. BUT --

My way of adding new shortcuts seems to be GONE.

I was in the middle of setting up a secondary profile with sync when the browser froze and became unresponsive for a few minutes. I killed the task and reopened the profile, it lacked the theme color I'd chosen and sync was not enabled. When trying to enable sync, I got the error message shown in the screenshot. To be clear, the profile it's asking me to switch to 'is' the profile I'm in. I've tried deleting the profile and the associated files from About:Profiles, but this issue persists.

I've also followed the steps contained in this issue and associated issues, but the profileID already matches: https://support.mozilla.org/en-US/questions/1581151

How can I resolve this so that I can sync this profile?

In a Private tab in strict mode (on Linux), I log into my Google account, then log out, clear all the cookies and cached data (Settings -> Privacy & Security -> Cookies and Site Data -> Clear Data -> tick all the boxes and clear everything), open a new private tab, go to the gmail website and it still remembers my account. However, if I quit Firefox and re-open it, then Google no longer remembers the account.

What information is deleted when I quit Firefox that is not deleted when I manually clear the cookies/cache/local data? Does anyone know why Google can still remember my account when I manually clear all the browsing data but not after I quit Firefox?

Thank you!

Hello, For about two or three days now, when I launch Firefox and try to open any website, it takes maybe one minute to load the page, then the navigation is OK on every website.

It only happens when I launch Firefox for the first time of my session. If I close it then relaunch it, it's still very swift.

I tried clear cache and remove cookies, just lost my logins lol but didn't work. I also tried with no extensions, nothing changed. Lastly I tried to set "network.captive-portal-service.enabled" to "false" in "about:config" but it didn't change anything neither.

So before I try anything else that could erase something on my profile, I'd rather ask here for some help :)

PS: running FF 153.0.4 on Debian Trixie with Mozilla repos. Only have two extensions: µblockOrigin and NoScript.

Thank you in advance!

Hi There are image display issues with Firefox. The attached image shows a screenshot comparing the same page on Glazy.org: Chrome on the left and Firefox on the right. The image appears too dark in Firefox, making it difficult to work using that browser. Is this a bug or a setting that needs adjusting? I haven't been able to find a solution. Thanks for your help.

I have used Firefox since version 1.5 and have loved it and the community since. However, since finally scrapping Windows and switching completely to linux, Firefox has been frequently troublesome with random crashes. The crashes occur on any website I may be on and for seemingly no reason. It happens when I'm in the middle of browsing a page, just opened a new tab, or even when Firefox is simply open and I'm active on another open application.

Environment is as follows:

OS: Zorin OS 18 (Latest patches) (Based on Ubuntu) Mobo: Asus Crosshair VI Hero (Latest available BIOS) CPU: Ryzen 9 5900XT GPU: EVGA GeForce RTX 3080 XC Gaming (10GB) Ram: 8GBx4 G.Skill TridentZ RGB DDR4 (3200) Sys Drive: Samsung 970Evo M.2 Nvme 500GB

Firefox is installed via Flatpack through the built in app store in Zorin OS.

The crashes will sometimes be constant as well. Such as when it crashes, crash reporter comes up, then I click "Restart Firefox" and the second I see the window, it crashes again. This has been a constant problem though at random times ever since I switched back to Linux about 5 months ago.

Any help would be greatly appreciated. I don't want to have to change my primary browser from one that I am generally so happy with, and is also the browser that I recommend to everyone.

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS
