Firefox Support Forum

""Many users with low vision rely on Windows' High Contrast Mode to make websites more readable. Traditionally, to increase the readability of text, Firefox has disabled background images when High Contrast Mode is enabled. With today’s release of Firefox 73, we introduce a “readability backplate” solution which places a block of background color between the text and background image. Now, websites in High Contrast Mode are more readable without disabling background images."

This "upgrade" has made unreadable many webpages. I have - for years - used a high-contrast screen color set-up: black background with white letters. I used to be able to control the on-screen colors of visited and unvisited links. That control went away a few "upgrades" ago.

This most recent upgrade, make all e-Bay pages unreadable: there are huge white areas, which used to be black.

How do I undo this "upgrade", so that Firefox no longer wrecks my screen-color set-up.

Note: I will not - under any circumstances - address a problem created by an upgrade, by changing my computer's settings, e.g., by editing registry files, etc.

Overnight it seems that Firefox is no longer reading my old saved logins and passwords. I have checked to see that the logins.json and key4.db files are present, but the new Lockwise page shows nothing. When I look at the about:protections page, it shows that I still have 400+ logins and passwords protected. I tried to make a new profile and import backup data and Firefox still does not see the saved logins and passwords in the new profile. Any ideas on what is causing this behavior? I have so many accounts, and would like to get this functionality working again.

when trying to open an outlook email it opens but all i get is a blank screen as the screen hangs with "https://outlook.live.com/mail/0/deeplink?version=2020022303.15&popoutv2=1&leanbootstrap=1"

This is a direct question as to whether Firefox saves any user NON DELETEABLE information. It appears Chrome does. These are not cookies or history as I know it. Presumably after Chrome has uploaded to a server somewhere it is then deleted or perhaps there is a timed or storage limit delete. The Chrome explanation is that "it makes the user experience faster and better". More likely is that google is increasingly being denied cookie & tracking data because of privacy addons or public opinion, they have a new way to get most of the same information. They just call it a "profile" rather than a cookie.

So firefox will not let me search with Google, Bing, DuckDuckgo. But Baidu works. It is saying that it is a security issue. And thanks to google header which is strict transport security it will not load. This is the full error code

Get this error when ill try to open this ADDONS MOZILLA WEBSITE (https://addons.mozilla.org/ru/firefox/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_content=find-more-link-bottom) Can i get some solution please? Thank you, Sergei

hello, this happens now every time i click a link to another site from an email. yes i want firefox to prevent the automatic redirection that some sites try to pull; but it should be obvious that when i click a link that i want to go there. (ie an email from discover card with a link to "view statement") links do work in other circumstances (ie a link to a youboob video from a wfmu comment board)

i've checked out the answers to this basic question and it is not solved. not for version 73.0.1 anyway.

in my preferences there is no "advanced" (except for fonts & colors); there is no "accessibility"...
someone suggested going to "about:config" and turning "blockautorefresh" to false. it seems like that might mess up some other functions...what's autorefresh got to do with redirecting? i do recall seeing the option "Warn me when web sites try to redirect or reload the page", but that must've been on an older firefox version, or on my ancient windows laptop, because i cannot find it now. 

            Thanks

When attempting to access https://signup.gmx.com I get the following error;

The requested URL was rejected. Please consult with your administrator. Your support ID is: < 3522328377538005653>

I contacted GMX and they have been unable to tell me why I can't access their signup page. I had my brother do a test from his home. He's on a different ISP. He is using a VPN, but this worked off VPN too. He is using the same ESR version of Firefox that I am, and he's on the same Windows 10 version I am. Also, he's using the same router I am with the same firmware. He can access the page without issue.

What I've tried;

• ipconfig /flishdns
• Checked my IP address is not blacklisted.
• reboot router
• power cycle NTD
• Run Firefox in safe mode
• Clear all cookies and cache data
• Create a new Firefox profile
• Disable Windows private and public firewall
• Rename hosts file
• Disable all firewalls in the router
• Tried different DNS Servers
• Tried different NICs (My PC has 3)
• Rebooted switches
• Checked PC for viruses/malware
• Tried different PCs in the same household
• Tried a different ISP
• Followed suggestion on https://appuals.com/how-to-fix-the-requested-url-was-rejected-please-consult-with-your-administrator-error-on-windows/ with the exception of "Add to trusted sites" I don't run any Microsoft browsers
• Read through this: https://support.mozilla.org/en-US/questions/1197304

I do not get this error for any other site. I've been trying to access this page on and off for about 6 months. It doesn't appear to be a temporary error.

Any ideas what might be causing this? thanks

Hello, Mozilla Firefox is my default browser and my favorite one

However, I have an issue when surfing on Youtube because at least one of the keyboard shortcuts cannot be used with Mozilla Firefox, while it works ok with both Internet Explorer and Microsoft Edge

Precisely, while on the French keyboard striking the "?" (question mark) key allows to reduce the speed of the video, the opposite shortcut "." (dot) does not works when it should increase the speed

Is there any technical conflict preventing for this dot shortcut to work, or was this forgotten in a way during the development phase?

In any case could it be possible to implement this in a next update?

Many thanks

I've read these instructions, I am more frustrated than ever. Why 2 places for bookmarks. Need help getting tabs on toolbar, including basic text, i.e. font. size, color, underline, bold, italics, etc. without getting kicked out of Outlook.live Email- smooth floating writing, background options for email. I need someone to sit next to me for a full day. Is it possible that Firefox and Microsoft 10, Office 365 are clashing?

SEARCH FILE TYPES AND APPLICATIONS (for downloads) I HAVE NO IDEA, Using Windows 7 was very easy, I just named the file in SAVE AS there was a drop down box for downloads, documents, etc. WHY WOULD anyone want their downloads in MS Outlook? As it stands now, I don't know where most of my downloads, documents, photos are located in Firefox. Even in Outlook 365 Word they are all over the place. DO NOT want them in Outlook Word, which is where they seem to go. I have selected web site addresses to download, instead of "save as" it wants the FILE TYPE. I hate every program on my PC, want Windows 7 back and Outlook 2013. I thought Firefox would be easier, heard good things, but right now I could throw it out the window. BTW, I have logged into Grammarly 4 times today, and once again it's asking me to login. I have more logins now than ever before in my computer lifetime. I'm not IT and an engineer, half the words used these days are Greek to me. Been working with computers for over 40 years, DOS, most of Windows programs or Apps or whatever they called these days, always a learning curve, but after 5 months, it's only gotten worse. Every phone call to MS support is a JOKE. 1 person says this, another persons says oh no this is what you need to do!! Printer no longer works after MS big PATCH. I dread calling HP again, but have no choice. Sorry I have just dumped all over you, but I am so angry with all of this I have screamed! I AM SENDING ANOTHER MESSAGE: I copy all messages from websites to Word just in case. When I just copied this information I will show you what came up, PRIME example of " what the hell". Of course, it may have disappeared by now!

New to Ubuntu and Firefox. Want to ditch Chrome. I have the existing extensions and a list of recommendations. I believe I have just the one add-on.

I've tried searching for the answer but think I may be asking the wrong question to diagnose the problem. YouTube plays just fine.

I have encountered: - This video file cannot be played.(Error Code: 102630) - No compatible source was found for this media.

Thanks for any help, Varices

When I try to access www.unofficialwarmoth.com using Firefox I got this error:

"An Error Has Occurred! Sorry Guest, you are banned from using this forum! bestkunmaza This ban is not set to expire. "

However, there are no issues if I access using Microsoft Edge. So, the problem lies within my Firefox.

I have contacted with the forum administrators and they can't find any reason why I should be blocked.

Any suggestion?

Thank you

When I started Firefox on my laptop (Windows 10 1909) this morning, Firefox noted that it was not the default browser. I clicked Set as Default, was taken to Settings and there was no default browser listed. When I clicked the button to set the default, Firefox was not listed (only Chrome, IE and Edge were there). I installed 73.0 last week but have been using my desktop most of the time since so I'm not sure when this changed. Firefox does appear in the installed apps list and is working normally when I open it. Did Microsoft do something that prevents Firefox from being the default browser? Is there another mechanism I can use to make Firefox the default?

Thanks for any help anyone can give me.

My bookmarks will not arrange manually even though I have followed the below instructions from the help guide to the letter. Everytime I drag and drop it somewhere in the folder, 10 seconds later, it moves itself back.

Rearranging manually

   Click the Library button 57 library icon on your toolbar. (If you don't see it there, click the menu button fx57menu then click Library.) Click Bookmarks and then click the Show All Bookmarks bar at the bottom.
   Click the folder that contains the bookmark you want to move to expand it.
   Click on the bookmark you want to move and then drag it to the position where you want to move it.
