Hi,

I'm on Arch Linux and use uinput to create key events. It works reliably for >12months in all applications and under all circumstances except in Firefox where some key events are skipped non-deterministically. My test case is:

in a text field, emit `<ctrl down>a<ctrl up>123456789987654321<left>...<left>` with 9 times `<left>`. Sometimes a 9 is missing and sometimes the cursor is further to the right than expected.

This happens every 8th try or so, which is too frequent to not break the user experience.

What I have tried: - multiple PCs (2 with this issue and 1 without) - Troubleshoot Mode - `window.onkeydown=(e)=>console.log(e)` (events are missing)

Since I've only ever seen repeated characters/keys disappear and never when writing manually, I would guess there is some kind of event cleanup algorithm kicking in. (the events are emitted without any delays)

I would really like to fix this issue because Firefox is my favorite browser. Any idea how to track it down?

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

With a recent update of Firefox Developer Edition to version 117.0b9 i keep getting extremely annoying popups on all sites, asking me if I want to translate stuff.

I don't want to store unnecessary settings in my browser, related to exceptions to websites/languages that I want vs. does not want to translate.

I want to completely disable translations, globally. Forever. Two questions:

- Why there is no "disable translations globally" checkbox in the newly added popup? - Is there an about:config hack to do disable translations globally, for all languages, for all websites, and forever?

thanks in advance

I am running Firefox-112.0(64bit) on Debian Bullseye. When I pend Firefox I am presented with a blank page rather that my normal sign in page.

Opening a terminal window and starting Firefox with /opt/firefox/firefox generates the following errors:

If I enter a URL the page opens and is usable.

How can this problem be fixed?

Thanks in advance.

I'm the tech director (tech janitor) for a public school that is using Securly.com for their Internet filter. Securly requires installing their own certificate so they can be a man-in-the-middle. I've installed that cert into Firefox and that works fine. However, even with that cert installed, Sync doesn't work when I'm behind that filter. As soon as I take one of my computers off the school network, everything will sync up. I don't get any errors that sync is failing, it's just not working. Any ideas on how I can fix that issue?

Thanks!

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

Same as the question.

The display shows some icons on the last tabs I opened but it seems only some basic website layout is loaded but all the details are gone. Like text, button borders, even the exit, fullscreen and minimize buttons. I have seen that this has been an issue for quite some time before so I am looking if there is a fix or a workaround. I have and Nvidia graphics card and drivers if that means anything. And my swap file is 20 GB and my RAM is 16 so the space shouldn't be a problem. It gets fixed when I turn off Firefox but not when I refresh tabs.

The crazy thing is that when I take a screenshot inside firefox (with firefox integrated screenshot option, like when I press right click and then take screenshot. I can see the text so it seems like it is a display problem but this only happens with firefox and not other apps.

Appreciate all the help. I will ask of ubuntu formums next if I don't find a solution here.

Thank you all for reading and answering!

nsandi.com asks for cookie permissions on every page despite accepting cookies on previous pages.

I raised this with them and they said it was because I am using an unsupported OS, I am using Ubuntu 22.04.3 LTS and FF 117.0 (64-bit) - which they do support.

If I use a different browser, Opera One(version: 102.0.4880.40) on the same machine it is not a problem.

Is there anyway I can make this work correctly using FF?

Hi,

I running Firefox on Ubuntu Lunar. Every thing is updated, Software Updater doesn't find anything to do. Neither does looking for updates in the extension manager.

I have a lot of extensions installed, probably too many. They include several malware, tracking, popup, and ad blockers. I'm surprised they seem to be playing well together without stepping on each other. When they do block something I need, it's hard to tell who blocked that and then fix it. Is there an easy way to find which one did the block?

Could the multiple blockers be interfering with each other in subtle ways without me noticing?

I have some false alarms where at first I thought extensions were interfering with each other. There are a few extensions that don't work: Dictionary Anywhere, Don't Track Me Google, and To Google Translate among others. When I click the puzzle piece extensions icon in upper right corner, they are grayed out and can't be used. I tried disabling all the other extensions and tried each one at a time by itself. They are still grayed out.

Any ideas?

(It may be "website broken" but I fear it is more this part of the problem)

Sorry folks, I know I don't help here much yet am often asking questions.

Base line: This machine Firefox Ubuntu 22.04 LTS Lots of pages/tabs open. 4 very specif tabs: 1 - this machine. 1 - RasPi #1 1 - RasPi #2 1 - RasPi #3 1 - RasPi #4

I use Node-Red on all 4 machines. So I have the tabs open on their "edit screen". I have a "dark theme" loaded - saves burning my eyes.

Until very recently things have been good. Example: Pic 1 And another part that is correct. Pic 2 All machines are running the same version of Node-Red with the same settings for how the "edit screen" is shown.

Suddenly - and alas I don't have a screen shot of one of the problems - the colour scheme is corrupt.

Example of a problem. Problem1 I can't see things until I move the mouse over them.

the other problem - which has now gone away - is the background as shown in pic2 is white.

Until today this problem didn't exist.

I am asking here as I want to check all possibilities.

SUSPICION 1: A LONG TIME ago I asked for help with the log in screen for these three remote machines. The colours were wrong and at the log in screen I was seeing text similar to how it looks in 'problem1' picture.

I adjusted the colours to something else and it helped the problem. Not exactly 100% good, but it did make the contrast better. Has that *crept into* causing this problem?

By opening a private window and logging in this is what the login screen looks like: login

Sorry I don't know how to make them appear as inline but I've named them as per how I called them here. (edit) SORRY, I see that the names were not exactly honored and they were given different names. I hope you can see what is what.

(edit 2) Ok, something else that doesn't make sense. The third of the remote machines. It's colour scheme is working fine. It is the same as the first two. RasPi. Buster. Ok 1 and 2 are V3 and 3 is V2.

BUT! Ok, saying what I just said/suspect is true: HOW did it happen? It was working for .... years. No problems. Suddenly **BANG** it happens.

Thanks in advance.

Hello.

Since some time (few months, can't really say when this started happening), the middle mouse button click on a tab stopped working as before. I will describe the expected behavior and how it (still) works on the same computer with a different browser (Chrome):

1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click closes a tab 5. Steps 2-4 may be repeated unless there are no tabs opened 6. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc)

Now, here is the not so great behavior I am facing in Firefox: 1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click rearranges the remaining tabs (increase their width, etc) 5. Middle-click closes a tab 6. Steps 2-5 may be repeated unless there are no tabs opened 7. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc), if you have left at last step 3

See, there is this extra step #4 which is really bugging me enough to actually come and ask for a support.

I am on Ubuntu 20.04, using latest version of Firefox (to date).

Many thanks!
