Firefox Support Forum

On a particular website we are developing we have a peculiar problem where CSS styles that we change are not applied at all at first (with a cleared cache of course), but only if we disable and then re-enable any CSS style on the site via the inspector in the developer tools.

And in some cases it looks like some CSS styles are sort of "messed up", i.e. there seem to be margins or paddings applied where they shouldn't be. And these problems go away as soon as you open the developer tools (or the inspector in particular).

Furthermore the inspector shows CSS styles that appear to have other CSS selectors as their content (see attached screenshot to see what I mean). While this looks like the underlying stylesheet has syntax errors: the stylesheet is fine and has been validated with https://jigsaw.w3.org/css-validator/ - so that shouldn't be the issue. Besides it works fine in Chrome and Safari.

I am at a loss how I could debug such an issue as I have never seen anything like it before. This only started to happen with FireFox 79.0 so I am wondering if other people have encountered something like this also.

Using Firefox 79 on Windows 10, all of a sudden I am getting requests to install an add-on identifying itself as slideclocks.com. I did not ask for it and every time I try to cancel by hitting the "Don't Allow" button, other windows pop up. It also seems to generate multiple Firefox windows, once I counted 18 of them. Doing an "end task" from the Task Manager doesn't help; they just pop back up. I tried reinstalling Firefox but the who process just repeated itself. I tried restarting with "firefox -safe" but that didn't seem to help. I also get a cmd window now and then with the same request to install slideclocks.com. Attached is a sample of multiple windows being generated by this add-on. So how can I get rid of it?

Slideclock comes up and (for me) no matter what I do it keeps cycling back and forth and nothing happens except confusion and more confusion. I can't get away from it... It's time vampire. I don't even know what it is.

Every couple of months I will start up my computer and find all my settings have changed and my Firefox add-ons are gone. I was not able to discern why but I made some changes in the configuration and got the text size back to what I wanted. This time it happened none of those configurations changed but I still had changed text size. I refreshed Firefox and found my add-ons immediately were reinstalled even though they were shown to be working when I checked my browser settings. One of the add-ons was Yahoo Mail ad blocker. I have used Yahoo Mail for years. Recently they have tried to make changes in my mail display to where I am being forced to go ad-free and upgrade to a mail subscription. After this most recent challenge to my computer setting, I am beginning to think Yahoo is disabling the Yahoo Ad Mail Blocker to get me to go to their subscription. Either that or Microsoft is challenging me to use their browser. It is like their is a war going on to win the internet. I miss the old Internet. Is there anything that can be done so my settings don't get hijacked?

firefox upload box shows file ordered by "modified". these files are in a different order than those displayed by Nemo. The files are all created at approximately the same moment. Nemo orders them correctly file1, file 2, file 3 etc.

I reset FF to latest, I believe to 79...now my FF home page has lost the FF logo above the search bar. Also when I go to my email and hit reply, the page below with mail I am replying to has turned to a grey background and when I try to paste a link to another site it disappears behind the grey,,,??!! It's still there but you cannot see it unless you scroll over it. I did a cache and history clean but no help. I'm using my local ISP email pkg. All works fine in Chrome...!!?? There is included here a screen snip of what I see when I hit 'reply'...before update the image was normal black text on white background

Any suggestions...?

FF v79.0 ubuntu 18.04.5

How do I change the font size of Firefox's webbrowser elements: menu, tabs, bookmark toolbar, etc. All things above the webpage window?

Most Videos aren't playing in Firefox - Netflix, Prime Video, Plex, etc....

YouTube is still working and it's hit and miss with other sources (mostly miss).

I have FireFox 79 and it's been updated for sometime before this started happening. I've not added any addons or plugins recently and my OS (Windows 10) hasn't updated lately.

Netflix Error: Error Code: F7355 IMDB Error: Error Code: 102630

the 'search function' does not work. By 'options/search/default search engine' there is nothing written; also 'one-click search options' is empty. What did go wrong?

Hello,

I recently purchased a monitor that I could hook up to my laptop when working from home, and yesterday after I connected the monitor I noticed that the scroll bar on the right side of the webpage was still there, but had gone completely black. If I click on it and drag my mouse, sometimes I randomly hit where the scroll bar is and it works, but I have no way of knowing where it is without guess and check. Also, the scroll bar does still show up on new tab pages and the firefox settings page. I was wondering if there's anyway I could either fix the problem or just stop displaying the scroll bar altogether?

Thanks

When opening Firefox to browse internet, is there a way that I can avoid going through Google completely? Currently, I go through Firefox to Google to Yahoo to browse internet. I would like to bypass Google entirely.

Hello,

Since the last update, I noticed that the check-boxes were not checked after clicking.
