Hello Firefox community

I use Firefox as my primary browser on 5 devices - personal desktop, work laptop, spouse desktop, spouse laptop, and personal laptop. On only my personal laptop, I frequently encounter SSL cert errors warning me of invalid issuer. I don't encounter the same error on any other device (including also my phones). Is there some way I can force an update of the Firefox certificate repository? I assume these are being caused by out of date cert repositories or the like. The cert I get on the other devices is the same cert presented to this laptop; only the laptop issues the error.

After Update, from 77.0 to 77.0.1 I am facing an issue. Now most of my YouTube videos are broken... I can hear but can not watch. It also happend with other websites. I reset, reinstall, cleared cache, removed extension to fix the problem.. but no result.

Noticed after a FireFox update I am unable to post picture comments to others posts on Facebook. GIFs and emojis are fine. Tried resetting Firefox and deleting extensions. No change. Restarted computer. No change. Can, however, post pics on other browsers like Chrome. Using updated Mac OS Catalina.

No ideas what else to try.

There appears to be a bug in Firefox when I use this website, https://www.ourguide.com.au/tv_guide.php?r=melbourne&w=now

When you scroll down, the headings move right and show above the wrong information, see attached screen shots.

If you use this website on Chrome, you don't get the scroll issue so I think it is either a Firefox bug or something that needs changing in my Firefox settings.

I am running Firefox 77.0.1 (64-bit).

Any help would be appreciated, thanks.

In my browser whenever I am opening non secure sites that are only like http://example.com it redirects to https://example.com and display the error. "Warning: Potential Security Risk Ahead" error. I could not know how to fix this error. This is happening all of a sudden. I could not find a way to fix this error.

Hello, Since 2 or 3 days, a connection to a web site is currently impossible because, there is an automatic redirection : http://192.168.1.1/login.lp... Can someone give me a solution to resolve this problem ? Thank you

Subject says it all - just about. When I attempt to open one particular website, I enter my userID and password and when screen opens it is not to the website selected but to a screen showing information about Oracle iPlanet Web Site. Cannot find a way to get past this screen. Been accessing this site daily for months without a hitch. A few weeks ago this happened one time. I closed FireFox and reopened and worked as it should . Then yesterday this started again and happens every time. Can access from Safari. Only install one new application recently, TotalAV but that was about 10 days ago.m Will attempt to add screen shot of what I see. The website I am attempting to access is in connection with my employer and I need to access it on at least a weekly basis. Other websites of my employer work fine. Please advise ehw

I use Firefox for my office, and there are several URLs internal to my company that work with a single word.

For example: "xyz/12345" is the same as "http://xyz.company.com/12345" which opens the resource 12345.

This used to work absolutely fine until the latest update.

Current: 78.0.1 (64-bit) on MAC OS 10.15.5

Now, xyz/12345 searches google instead of navigating to the website. I do still need google search on the browser bar, as I use it frequently as well.

Having to type out http://xyz/12345 is an overhead that I would like to avoid.

Please suggest if there are any workarounds that could be used to get this working again.

Hello, Firefox seems to be using my system's High Contrast text color to render websites. My High Contrast text color is a light grey, to contrast with a dark system background. However, many webpages on the internet have light backgrounds, so when Firefox uses this color, I can't read the text. I already have Options>Language and Appearance>Colors>Override the colors specified by the page set to "Never." This also occurs in a brand new profile with 0 extensions or addons in Safe Mode. I just want Firefox to display webpages "normally", i.e. with black text, without regard to the current system colors.

To reproduce: - Turn on High Contrast - Visit a site such as http://hyperphysics.phy-astr.gsu.edu/hbase/ppois.html - Change system High Contrast text color to any color you wish - Notice that the text on the page also changes to the same color, even with the setting on "Never"

Is there any way I can get Firefox to ignore the system's text color settings? Chrome renders the webpage just fine with black text.

Since the latest updates, I can't access at least two sites I need to go to daily. (chase.com and constantcontact.com) All other sites open fine and those two open in Chrome. I read that this is a known issue with the update. I don't understand the fixes. I just need things to work!

I have a mac with a free Avaast app running. Not aware of any firewalls.

Error says: "The connection has timed out" in both cases.

We use LogMeIn Pro for remote access to our office computers. When one selects Remote Control, LMI uses javascript to call the LogMeIn client. Except in Firefox. It works perfectly well in Chrome, IE 11, and Edge. It USED to work in Firefox. What gives? What next? Javascript is enabled.

Colors are distorted in MP4 video as you can see in the attached screenshot. The distorted colors impact video on many sites including yourlearning.ibm.com, webex.com, twitter.com, mlb.com, etc. They do not impact youtube.com which displays video correctly. My Firefox version is 68.10.0esr (64-bit) and my OS is RHEL 7.8, kernel version 3.10.0-1127.13.1.el7.x86_64, Gnome Version 3.28.2

I have tried running in safe mode but the issue persists.

How do get Firefox to display MP4 video with correct colors?

Every search I perform using google is being hyjacked by yahoo. I have read that many other users are having the same problem. I have tried to follow the steps to remove the add-on or extension but when I click on "add-ons" or extensions from the menu it just opens a new blank tab in my browser. When I click on search in the preferences menu, google is the only search engine checked in all of my selections. Please help me get rid of the yahoo search.

Hi,

I'm a web designer, I love firefox for develop my projects, one of the things that I love is that when i change a property value and I reload the page (F5) file css are ever updated,

Only in some cases with .js files I had to use ctrl+F5,

but now every modify I do then I hat to use ctrl+F5, why??

Has the behaviour of Firefox with regard to caching style sheets changed in the newest version?

I ask since I develop with Visual Studio and browse the development build with Firefox. Hence the URL will be similar to:

http://localhost:55223

If I modify a css file in the build and refresh the page in Firefox it does not change. It never changes even after a CTRL+F5, nor after starting a new session.

If I browse the site with Edge it does pick up the change instantly after tapping F5 to reload. To see the changes in Firefox it's necessary to rename the css file to force a reload of it.

This only seems to have started happening since the latest build and makes it impossible to use Firefox in the development environment. Is there a "hack" for the settings to force a reload?

hi. recently I have found that I can't load ebay correctly on Firefox, it loads fine on Edge. Other websites appear OK. I don't know how to describe the appearance - there are no images, only various numbered headings, and highlighted links.( I have taken a screenshot, but don't know how to save it in a format that can be loaded on to this page!). It has only been a problem for a few days. What to do??

everytime i load ebay.co.uk the page doesnt display correctly. I have tried deleting cookies and data and reloading firefox but it is still the same. I have also tried loading on chrome and it displays perfectly.
