Firefox Support Forum

Following site is immediately hijacked to a scam site asking for login apparently to access private info. It happens with Firefox (only) whenever security setups are set "not to track", "not to prompt for passwords", "not to prompt for credit cards" "no history" "reset of cookies at logout" etc.. then the site below: http://thaimassage-herborn.de/ is redirected to SCAM SITE: https://xb7.serverdomain.org/admin/index.php appearing as "Adminpanel" asking for Login etc..

At the same time following site is partially blocked on the news banner pictures, with a white sheet over them, whenever down scroll is hit. https://www.tgrthaber.com.tr/

Only by resetting firefox deals with the issues. But ofcourse with the reason, above security settings removed.

Virusscanner was not able to detect this hijacking or the reason behind.

Is this a firefox software issue? Is there a way to resolve this? Thank you already for any support or suggestions to resolve.

Accidentally added a misspelling to the Firefox dictionary. Thought it would be easy to locate and edit the dictionary.

Enabled 'show hidden files.'

On XYplorer, and Windows File Explorer can find not a single trace of 'persdict.dat' in my profiles folder.

It would be really helpful if you could advise what the next step would be. Thanks.

Couple days ago Yahoo Mail stopped downloading attachments of any type. Only happens when using Mozilla. Yahoo mail works fine with edge and android. The following had no affect: (1) signing out and in to yahoo mail. (2) Clearing cache etc in Mozilla (3) rolling back recent windows updates. Occurs with all types of attachments, so not an app issue. Appreciate your help, please include only those suggestions which consider the "suddenly" part...

Hello, Every time I restart Firefox or it crashes or power cuts or anything, place.sqlite file gets corrupted and I have to replace the new file with the .corrupt file. This has been happening for over a year now, but my computer is always on and I turn it off maybe once every 4-5 months unless I'm forced to restart by a software or by power cuts or stuff. Lately I have been having issues with my Windows and I have to restart my computer quite often and it is very annoying. This happens whether I close Firefox with the X or using the Exit button or even if I keep it open and restart the computer. My places file is 75MBs. I have the same one since 2014. I'm using Windows 10 and latest Firefox edition. Any ideas?

I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Hi: I've used Firefox for years without trouble and I've even given money! However, I think the last update has prevented my banking site from operating correctly. In Bill payment you choose who you want to pay and fill in the amount. This still works. I move to the month, day, year boxes. If I click, say, on the month box I get a dropdown but selecting the month nothing happens. Ditto with day and year. The day box shows 1 and the year shows 202 and nothing changes when using the drop downs. Can't manually fill in the boxes. At first I thought it was my bank but they said there were no reported problems - they would! So tried Brave and Edge. Both worked perfectly. Tried it on my laptop rather than desktop and same problem using Firefox showed up. I hadn't fiddled with any Firefox settings. What to do? Thanks Donald

Every week, for work, I need to download at least one large video file from Microsoft OneDrive and then upload it to YouTube. (These are MP4s in the range of 200 - 800 MB.) For the last couple of months, maybe longer, the download keeps failing in Firefox. When I switch to Chrome, the same MP4 downloads with no problem.

Any idea what might be going on? Usually the file starts downloading just fine; I see the bar gradually filling up in the notification area, but then it suddenly stops and says "Failed." If I retry, the same thing just happens again.

I'm not using any kind of download manager (that I'm aware of), just relying on Firefox's default download behavior when I click on the "Download" link on the OneDrive web page (sample URL: https://olucdenver-my.sharepoint.com/personal/YADA_YADA/_layouts/15/onedrive.aspx?id=LONG_QUERY_STRING_HERE).

Thanks in advance for any help you can provide!

In trying to reach at least one Web site (maybe more), https://jabberwocking.com/, I get an error page, Error 523: Origin is unreachable. It also has some tech stuff I don't understand. What can I do?

Firefox keeps disabling addons randomly, some of them are made by mozilla even. I am getting them from the official addon site so they shouldn't be illegitimate ones. Let me know what information about my install I can give to help.

OS version: windows 22000.593 Firefox version: 99.0.1 (64-bit)

I have been successfully using FireFox for many years, recently we downsized into a Condo,now 81 years young. I have FireFox as my default browser choice, but it only lists Google on the search bar, when I type in my search in the box under the Firefox name it immediately jumps up to the top of the page Google browser.

How do I get back my screen to use FireFox as my search engine ?? I have tried to change it but will only give me two options Google or Google ?? Is it possible to go back to the screen and try and start again??

Many thanks to anyone who will give me info as to how to rectify my problem, be gentle with me as I am efficient in using the computer but less so trying to solve my problems. Robin

I've run into a troublesome error with Firefox for probably eight months now, so I have not been using the browser. Whenever I attempt to install ANY add-on from the Firefox add-ons page, I get the message "[Add-on name] could not be installed because Firefox could not modify the needed file". Furthermore, attempting to download the add-on file manually (should it be available on a github page or the like) leads to the same message or a notification that the download failed.

As a matter of fact, downloading almost any kind of file on Firefox inevitably fails. The exact notification is shown in the upper-right corner of the browser window, where downloads are shown, and beneath the file in question is an indicator that says "Failed". Everything from .png to .zip to .exe appears in the downloads queue for a second, then fails.

I have tried every solution the Firefox add-on troubleshooting page has suggested, including solutions suggested in other threads, such as deleting/creating new profiles. I have also attempted to completely reinstall Firefox on multiple occasions, as well as the refresh Firefox option.

To recount, the following troubleshoot solutions did not work:

--Everything on the Firefox add-on troubleshooting page --Restart Firefox --Refresh Firefox --Create new Firefox profile and attempt to install add-ons from there --Delete and renew the extensions* files from the profile root folder --Modifying the xpinstall.signatures.required in about:config (true or false, doesn't matter) --Modifying the extensions.alwaysUnpack in about:config (again, true or false, doesn't matter) --Double-checking allow list and permissions on local firewall and antivirus software (the app is protected, add-ons are allowed) --Disabling antivirus software --Running Firefox as Administrator --Reinstall Firefox --Restarting PC

If I want to download a file or add an extension, I need to switch to a different browser such as a chromium-based one or Microsoft Edge to download the file. In the case of add-ons, I switch browsers, download the file, and select the "install add-on from file" option under "manage extensions" in about:addons.

One final thing. It seems that sometimes streaming sites won't work on Firefox (even with ad-blocker disabled or the site allowed through the ad-blocker), and sometimes video won't properly load either. These things work fine on other browsers.

I really like Firefox as a browser and enjoy the privacy it provides built-in. I didn't have any of these issues up until last year and I was forced to switch over. I would really appreciate any help with this.

I am on Linux Mint, Firefox 100.0 and I am trying to access a website, https://www.citapreviadnie.es:38188 (requires personal DNIe certificate). However, I keep getting SSL_ERROR_UNKNOWN_CA_ALERT. If I view the certificate of the website,

1. Firefox doesn't tell me which part of the chain is invalid or not trusted (or I don't see it) 2. When I try to download and import each of the CA certificates, I get an alert saying "This certificate is already installed as a certificate authority." 3. If I try to import the whole chain, I get another alert telling me "This is not a certificate authority certificate, so it can’t be imported into the certificate authority list." 4. If I try to add a permanent exception to the site, I see "This site attempts to identify itself with invalid information", but if I click "view certificate" I'm back to step 1, and adding the exception does not have any effect.

What am I supposed to do now?

The title already says it all. Whenever i have some sound or video running in any tab, clicking on certain things like other videos or animated stuff in the same tab or another one causes a small interruption in the sound/video. Clicking a lot of times results in sound and video stuttering. I does not appear when i just click another link.

I already tried updating firefox, reinstall firefox, even downgrading firefox. This problem only appears in firefox and only on this device. I would be very thankfull for some advices, because this is really annoying.

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley

While using Yahoo email I tried to access the 'Notepad' page and get a message saying to Download a new version of Firefox to see the 'Calendar' even though I was trying for the 'Notepad' not the 'Calendar'. If I try for the 'Calendar' I initially get the small right-sidebar version fine but if I ask for the full page version I get the error message again. This does not happen if I access Yahoo through Chrome-browser. I have repeatedly done the download to no avail. (I have version 99.0.1). I am attaching a screenshot of the error message. Thanks for any help. No rush.

Hi,

I'm trying to access my Apple ID (appleid.apple.com). When I select "Sign In" the page hangs and never displays the fields to enter my user name and password. The message I get is "This action could not be completed because of an error. Try again or check back later."

Under Settings > General > Network Settings I selected No proxy and I disabled DNS over HTTPS. But neither of these actions made a difference.

Eventually, I had to use Microsoft Edge to access my account.

Any ideas?

Thanks!
