Firefox-Hilfeforum

A site that I use several times every year recently wouldn't open. Response from Firefox is "Access Denied - Certificate issuer not recognized". Also kept getting bumped out of my email account and all my open tabs would close abruptly. The last may have been rectified but I still can't get into the website I want to access.

I've tried different browsers as well so I don't know if it's Mozilla only or my PC. Even if I type in https://www.(pagename).com, it displays as you don't have permission to access http://www.(pagename).com.

I changed nothing on my PC that would cause the problem.

This issue is with me for some time now I guess 6 to 12 months, I have circumvented it by simply using other browsers that don't have the issue, it is only in Firefox.

I have noticed that it seems to be a reoccurring issue for many people reading through help topics.

At the moment I am using: Mozilla Ubuntu Firefox 91.0

 Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Starting Firefox in "Safe mode/Troubleshooting mode" through the "Application menu" -> "Help" -> "Troubleshoot Mode", doesn't fix the problem.

... "Did you check the date/time and time zone on your computer?" (As suggested in an older topic)

Automatic synchronization with an Internet time server, is set to "ON"
My "Time Zone" is set manually set to the correct "Time Zone"

Since the issue is only in Firefox and not in Chrome, Chromium or Opera, there is something that Firefox is doing that Cloudflare doesn't like or visa versa....

I have noticed in other posts that the blame is simply shifted to Cloudflare, but why do other browsers then not have this problem ?

Opening the no longer existing website (from another help topic here about the same issue), that is still known by Cloudflare, shows the problem if you got it too -> http://animedao.com/

See my uploaded screenshot to see it is only in Firefox.

I don't why (as i have not altered any settings). But now when i use Mozilla firefox browser, a lot of websites are being displayed with a blark/dark background. I know it is the firefox browser as it does not do the same if i use other web browsers. I tried looking up the issue and solutions. All i could find was some suggestion that websites are displayed according to the settings on my PC i.e if it is set to light or dark mode. I checked this and the settings have not changed. Also as previously mentioned, then if that was the reason, surely the websites would display dark when using another browser. I have attached a screen shot of the twitter website as an example.

I am a HTML, PHP developer, but lately I am going crazy because the browser doesn't refresh the page when I make changes in the code, apparently the page is refreshed from cache and is not showing the changes. Could You fix that Please. I tried the recommendations of press Shift and the refresh button and the Control, Shift, R, key combination, but that doesn't work. Thank You Very Much.

Since a few days, when I visit Google Maps, after completely loading the page (roads and buildings shown for a brief moment) the map becomes wholly black with just captions still readable.

Doing the following didn't fix: Restart Firefox. Update Nvidia Drivers (updated yesterday to 466.11, didn't resolve). Disable every add-on and setting default theme. Disable Hardware Acceleration from settings.

THIS temporarily fixed: Entering Firefox Troubleshoot mode.

So I assume the problem is in advanced settings. There are TONS of settings there. Any ideas? I 'd rather not go through a Firefox Refresh losing all site permissions/fine tuning for cookie settings/blocked content for every site made in years. I'm on Firefox 88, Windows 10 64bit ver. 2004, GeForce 950M, Core i7-4720HQ, 16GB RAM.

I put "again" in the title since another question about this is marked as solved for Firefox 68/69. Needless to say, I tried everything from that discussion (such as switching gfx.webrender.all), to no avail for the present issue.

firefox is my default browser but every time i want to open a website or my gmail i have to sign in to google first . always get a message from google stating that cookies are disabled on firefox browser and i must reverse this and make google my default browser . what then is the point of firefox if i have to do this every time i may as well stay with google chrome . how do i solve this so that i can log on to gmail and autotrader with firefox .

Hi i can't open twitter for some reason it keep giving me twitter.com/?failedScript=polyfills I tried to refresh Firefox and delete cache and it still didn't work I can still open twitter using different browser can anyone help me?

I recently deleted all cookies & site data & now whenever I search for something using Google I get the following message (below) where I also have to fill out a Captcha in order to proceed. This only happens with Firefox. On the same computer I have Microsoft Edge which has no problem with Google search. What's the problem with Firefox? Will give up this browser if this continues.

I contacted the Daily Mail newspaper because I keep getting their popup news alert messages even when I am reading my email. My Firefox popup blocker is checked. I complained to the news paper and they gave the following message to get rid of these annoying messages. Here are their instructions to stop this on Firefox> 1. Click the Settings icon in the top right of your browser window and choose "Preferences" 2.From the left hand side of the page, choose "Content" 3. Under Notifications, press "Choose

There is no Preferences category under my settings icon. There is no Content on the left side of the page when I go to Settings There is no Notifications label from which to select Choose.

How the heck do I get rid of this annoying popup or notification or whatever the heck it is? Please advise. Thx

The other day I downloaded SaveFrom.net Helper but then shortly after I deleted it. The program was deleted from the computer except that the green line with the program name shows as an extension on the bar at the top of the Firefox page.

I cannot delete it. If I delete it once it reappears next time I load Firefox. The extension does not show up in add ons and extensions in Tools Firefox.

I have read an earlier reply that suggests delete Firefox and reinstall Firefox and that will get rid of it.

However, I am not anxious to try that as over time I have already extensions ad add ons and other customisation of Firefox, including all my bookmarks and I don't want to lose these and start again.

So here is my question. As the program is deleted and as their extension does not show up in Tools and then adddons, can I assume that the existence of the program name as an extension on one of the title bars at the top of Firefox is just an irritation and that this SaveFrom program cannot in any way add or do anything to my computer?

I can then live with it rather than deleting Firefox and starting again.

I would be so grateful for your help.

Thank you.

Ive never noticed this until last night but how come when i use a theme it controls whether website pages i browse will be light theme or dark theme? is there a way to turn this off? I have a theme on rn and i like it but i cant use firefox atm because certain websites i browse show up as dark theme and i hate that i just want them all to be light theme. Thanks for the help in advance.

Hello, I have problem playing nba matches on watch.nba.com (all the videos on the website included) I can play them fine in chrome and edge but firefox seems unable , when I click watch nothing happens. it stays in the same page and the same layout

Whenever I go to Amazon.com the site displays in a micro format (about 20% of the screen in the center), too small to read at all. Yet if I use Internet Explorer I do not have these issues. I have cleared my cache etc (no luck) How do I fix it.

I continue to get access denied messages when going to common websites. You don't have permission to access "http://www.fredmeyer.com/savings/cl/coupons/?" on this server. ''Reference#18.d793517.1649002062.289635e4 This doesn't make sense - this is a site I go to frequently & don't understand why I continue to have problems - I followed some suggested fixes yesterday & it seemed to work again until this morning. I also got a message when I tried to access Amazon that indicated the connection was not secure. I rebooted the laptop & that fixed Amazon problem but not this Access denied problem - Your browser might be a little too safe if it can't connect to common websites

Starting as of today (Oct 13), the FACEBOOK screen suddenly moves when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts about a page up, closer to top. This shifts the entry area where I'm typing down and off the screen. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. It is maddening!

I've restarted in troubleshoot mode and the same thing happens, so it is not an add-on. This is happening on both my Firefox Linux systems AND on a Windows 10 machine, so I don't think it is specifically OS related either. The screen however does stay put, like it is supposed to, using Chrome or Opera.

Is this a Firefox problem or is FACEBOOK messing with Firefox?

When I load Amazon.com, the webpage is a lot of text and random pictures. Amazon's layout is broken. I loaded the same page in Chrome and Safari without a problem. I reinstalled Firefox 99.0.1 without any improvement. Please fix.

Yesterday I started having trouble logging into Gmail and associated apps (calendar, contacts, docs, sheets, shared folders, etc., as well as google.com) in Firefox. All other sites are loading with no problems. Google apps are working fine in Chrome. Still having problems today.

My office uses Google Workplace for everything so this is really messing me up, I've lost several hours of work trying to get things to load. The IT person told me that if Firefox is having problems I should use Chrome instead. I hate Chrome! I want to use Firefox, but I can't get my work done if it won't load Google apps.

Please note that I have tried the following solutions thus far: restarted Firefox (several times) restarted computer removed add-ons cleared cached web content cleared cookies and site data refreshed Firefox solution at https://support.mozilla.org/en-US/questions/1200943 solution at https://support.mozilla.org/en-US/questions/1132284 solution at https://knowtechie.com/is-mozilla-firefox-not-loading-pages-for-you-heres-the-fix/

After each fix things start working for a while but then everything Gmail-related freezes or crashes and I need to start all over again. Help!!!

I'm running Linux Ubuntu 20.4

Whenever I try to use a website that has a browse button (e.g. youtube uploader, google drive, etc) I click it but nothing happens, no file browser comes up.

As per previous discussions on this issue, I have tried Safe mode, refresh (in fact total new operating system and re-install of firefox) and disabling hardware acceleration, even turning off popup blocker and none of these have made any difference.
