Firefox Support Forum

I was having trouble with a website so went to Mozilla for help. Followed some of the instructions for removing cookies. Somehow ALL of my email folders have disappeared. Literally decades of saved emails. PLEASE HELP!

Hello,

The next message/previous message arrows that appear at the top of an open email in Hotmail.com is being blocked by Firefox. I checked Hotmail through another browser and they are not blocked. I tried refreshing Firefox and they were still blocked. I've opened Firefox without add-ons and they are still blocked. I'm at a loss as to how to get them back. They were there last week and then vanished only to come back on Friday and vanish again while I was reading emails. From time to time Firefox also blocks images in Hotmail and I just have to wait and eventually they return. I'm at a loss as to understand why these things are happening so frequently with Firefox and Hotmail.

Please help return Hotmail to the way it was before the last update.

Thanks,

Brian Himes

I have been using Firefox as my default browser for many years and much prefer it to the other browsers. However, several weeks ago Firefox started blocking the download of my morning newspaper. Now I have to copy the link from my morning newspaper email and paste it into Chrome to get access to my newspaper rather than simply clicking the link in the email. While I found this very annoying, when I couldn't find a workaround, I just continued to copy/paste into Chrome. Today I tried to download my IRA quarterly statement and found Firefox is blocking this pdf download also. Note that in neither case does Firefox tell me that they are blocking the downloads and they just do not download and some pdfs do download. So this is now getting beyond just annoying. Is there a workaround for this new Firefox problem or is my only alternative to define Chrome or Edge as my default browser and give up Firefox?

I am suddenly getting a number of web sites, which I have visited in the past and I know to be valid and secure, giving the Secure Connection Failed errors. Have you changed the programming behind Firefox which iis causing these problems. How am I supposed to get to the web sites with no ability to over ride the failure?

Is it possible to turn off EVERY signle certificate check/verification in firefox?

1. "Error code: SEC_ERROR_BAD_SIGNATURE"
2. "Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT"
3. "Bulleted list itemMOZILLA_PKIX_ERROR_MITM_DETECTED"
4. "SSL_ERROR_BAD_CERT_DOMAIN"
5. "SEC_ERROR_UNKNOWN_ISSUER"
6. "etc etc... EVERY single certificate check!"

In the past it was really easy just start with "--ignore-certificate-errors". Now it's like moon landing, all options are hidden or have under a hundrred layer option list. Anything in the "about:config" ? browser.ssl_override_behavior 1 security.ssl.enable_ocsp_stapling false

(Please do NOT comment its unsafe and other things, that's not what I'm looking for)

Hello, I need your help and support. I put in steps what i had done.

1. I had a sync in my account dchisinska-br@o2.pl 2. Format C: without extracting my profile 3. After reinstal Win10 I wanted to sync but forgot the password 4. Reset password, BUT didnt know that when I change my password without Recovery Key all will be lost. 5. When I realized that this happened I found a profile from 2019. 6. Every time when I copy data form old profile to new profile browser want to refresh and whole profile is clear withou data. 7. Also I opened Help->more tools for Troubleshooting information -> Profile folder -> Open -> COPY from old to new. Nothing happened. Still have nothing.

I lost all my password, history and everything.

Please help or how to solve this problem. Or maybe you can recover data from SYNC which is missing after changing password to my mozilla account.

Thank you, Danuta

When I ask WordPress to "preview in new tab," I get a File Not Found screen. (See uploaded image.) This works fine in Chrome (which I rarely use) but not in Firefox, so I'm thinking it might be a Firefox issue. The Tablet and Mobile previews work fine, but they don't require a new tab. I thought it might have to do with pop-ups, so I made my blog's URL an exception. That didn't help. Then I disabled the pop-up blocker altogether. That didn't help either. I've never had this problem before although I've been using both Firefox and WordPress for many years. I'm working on an old laptop (current one is kaput), but I think everything's up to date. Windows 10. Any idea what the problem might be? TIA for any help. This is driving me nuts!

Hi, After the last update Firefox asks me what I want to do with the pdf files and to choose between Open in browser, Open with and Save file but even if I choose Open in Firefox it always downloads the file in the download folder of the PC and then opens it, This is really annoying because then I have to delete them manually. What can I do? Thank you

Bonjour,

Lorsque j'ouvre Firefox, deux pages s'ouvrent: - le gestionnaire de modules; - Beautiful GX Fantasy. Si je supprime ces pages, elles reviennent à l'ouverture suivante. Merci de m'aider. Cordialement.

On certain (very few) web sites, I get a symbols font showing instead of text. For example on www.xe.com I have tried a refresh already, disabled addons etc..

Weirdly, THIS support form suffers from it so I am attaching pictures to illustrate the issue.

I have googled the usual stuff to no avail, so really stuck now...

many thanks for any pointers, Lozzy

I wanted to know to how to fix this issue.

cipher suite which I have set are - TLS_RSA_WITH_AES_256_CBC_SHA384,TLS_RSA_WITH_AES_256_CBC_SHA256

Please help me with this

My Last Pass add-on was disabled after the last update of Firefox and when I removed it and tried to reinstall, the message was that the file was corrupted. What do I do?

I use firefox for reading pdfs a lot, and i would really like to use page up and page down for their proper functions when doing so rather than having to scroll. the issue is these keys dont move a full page height, they are slightly too small. thus the pages quickly become misaligned requiring scrolling to rectify. a very minor but very annoying problem that i assume has a simple fix but i cant figure it out. help with this would be greatly appreciated!

I'm not sure what is causing this, but it started at least a few months ago. I will be using firefox, and anywhere between a few minutes, or a few days, it will suddenly stop loading anything and I will have to completely quit it and restart it to get anything working again. No, it is not the HTTP3 problem; that was the first thing I tried. I've also uninstalled, and reinstalled the entire program, clearing all settings, etc. I am on windows. Generally good on firefox updates, will check and update usually every week or two.

Funny thing is, I also installed firefox nightly and that does not have this problem (although I have not used it as extensively as I normally do when browsing, so maybe I didn't hit whatever triggers this issue). It also works properly on other computers (as far as I'm aware). So I still think something is corrupt or wrong with my normal firefox program. I just don't know what or how.

Because many websites ignore my choice of a dark theme (both in Windows and in Firefox) I tried using color management in my Firefox Settings to force white text on a black background. This had the desired effect on websites, but unfortunately also applies to plug-ins, some of which (like uMatrix) depend on changes of background color to convey information or have dark icons which become invisible on the dark background. Is there any way I can have my cake and eat it too?

It's June 2022, and I am using FF64 101.0.1.

My issue is best described by Zaayl (2017) at https://support.mozilla.org/en-US/questions/1157490, but the working and easiest solution I found was the one offered by delclemons (2018) at https://support.mozilla.org/en-US/questions/1229621#question-reply.

My starting page is blank. I have an extension that shows my external IP as a country flag when FF starts up. If the flag doesn't show, I know I still cannot connect to any site. Similar to Zaayl's case, my FF can be able to connect to sites only after a certain amount of time, which varies from instant - very rarely - up to over 10 minutes. The wait always gets longer, especially when FF crashes and have to restart.

I've been searching a long, long time for the right fix. I cringe at the idea that I have to reinstall FF every time there's a major issue, like this one. Syncing back bookmarks and passwords and reinstalling the extensions are the easy part. The painful part is having to set details of accounts in the containers afterwards. I am so glad that is over now. Connection to sites is no longer prolonged after FF startup.

I wanted to thank the persons concerned, but I couldn't reply to their messages, which are now archived. So, I decided to post a new one here to do that; also, to help users who have to same issue as mine.

i lost my previous tabs and i couldnt recover them. they were no were to be found in history. i need to restore tabs to a previous time or date to recover them and there is no such option, as i accidently closed the new tab and now its overwritten " previous" tabs.
