Firefox-Hilfeforum

I have been getting the following error message on various websites, including Google, Deviantart and others:

Network Protocol Error

Firefox has experienced a network protocol violation that cannot be repaired.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the web site owners to inform them of this problem.

Refreshing the page makes the page load properly, but the error keeps occuring.

I'm using Firefox version 65.0, which seems to be up to date. I have tried reinstalling Firefox and creating a new profile, but the problem persists. My Windows version is 8.1. I am currently using the following add-ons: McAfee WebAdvisor version 7.0.0.17912 uBlock Origin version 1.18.4

Possibly related: some sites are not displaying image thumbnails on first load, or are displaying them incorrectly; e.g., Youtube will sometimes display the thumbnails from a previous search on a new search.

Any help will be apprectiated, thanks in advance.

Hey, guys. I got a new laptop as a christmas present, and have been trying to synch bookmarks between my old craptop and it. Surprise surprise, the craptop is erroring when I try to synch. I have the error log here, but, as I am new to the site, don't know how to add it to my post, other than by copy/pasting the contents, and it is too long to do that. So... might need to let me know how to do that. Sorry.

We built a WordPress page with various graphs to display data using the Tableau app, it works great on Chrome and Edge but when we went to test it on Firefox we got an error message and the graphs won't display. Any idea why or how we can fix it?

Webpage (graphs are in the toggles): https://www.somervision2040.com/somervision-numbers/ Error message: http://www.somervision2040.com/wp-content/uploads/sites/3/2018/11/error.png

On one of our machines, we get the message

> The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

According to the user, this started after we upgraded the machine to MacOS 10.14 Mojave. We already tried to

• restart the computer
• start Firefox in safe mode
• reinstall Firefox
• move places.sqlite to have Firefox create a new one
• create a new profile
• refresh Firefox
• granted Firefox full disk access under "System Preferences - Security & Privacy - Privacy"

all without success. I even tried to open places.sqlite with sqlite3, but wasn't able to find any tables, despite the file being +500kb.

The integrity verification of the places database produced the following output:

Task: checkIntegrity - Unable to check places.sqlite integrity: Error: Could not open connection to /home/g001570/Library/Application Support/Firefox/Profiles/scuoog8q.default-1541591890759/places.sqlite: 2153971714

> Task: invalidateCaches - The task queue was cleared by an error in another task.

> Task: checkCoherence - The task queue was cleared by an error in another task.

> Task: expire - The task queue was cleared by an error in another task.

> Task: originFrecencyStats - The task queue was cleared by an error in another task.

> Task: vacuum - The task queue was cleared by an error in another task.

> Task: stats - The task queue was cleared by an error in another task.

> Task: _refreshUI - The task queue was cleared by an error in another task.

This error code (0x80630002) leads me to "NS_ERROR_STORAGE_IOERR". Is this a correct assumption?

I'm wondering whether there are ways to find the original error that caused Firefox to show this error message (like "could not open file xy"), or is there a debug log that can be used to get more information about this problem? What's also puzzling me is the fact that this error persists even with a new profile or a fresh install.

Any help or advice appreciated. Thanks in advance.

my firefox in my computer doesn't sync the bookmarks, and I typed :about:sync-log and I opened the last file: error-sync-1540522066731.txt

it shows:

what should I do now?

I have several system that all use Firefox and are configured to use sync. All of them, but this one sync fine. The one with the issue is on a RHEL 7.5 host and is running FireFox 52.8.0. What is odd is that I was able to register the system with sync, but when I click on the sync icon, nothing happens. The sync logs indicate some errors:

Jon

can someone tell me the about:config setting for toggling show error page or popup when firefox cannot connect to some site i spent hours finding this on google now the setting has reveted back and i dont remeber I HATE FIREFOX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

After upgrading to 33.03, I get an error message whenever I try to quit or restart saying "Cancel All Downloads? If you quit now, 72 downloads will be canceled. Are you sure you want to quit?" with buttons saying "Don't Quit" and "Cancel 72 Downloads"

I absolutely do NOT want to cancel ANY downloads, but I seem to be stuck. There is some urgency because my area in Maryland has frequent power failures, and the least short-term power fluctuation will cause my iMac to restart, causing me to lose hours of choosing and downloading graphics files. What can I do?

Every time I try to visit any site via firefox I'm getting "This connection is untrusted" error code: sec_error_unknown_issuer

Yes my date and time settings are correct. I tried deleting the cert8.db file like the help page said and it's still doing it. I am technologically challenged so I would really appreciate it if someone would explain the solution to me in terms a rock could understand. Please and thanks.

My (Your) screen resolution is set below our minimum recommendation of 1025x600 pixels-for a better experience, try increasing your screen resolution. Try again. You may continue with your current settings, but Frontier-Yahoo may not display properly. I cannot access Frontier Email account. Windows 8 OS. Advise Please. I have tried uninstall/install Firefox with no solution. How do you increase screen resolution? Thank You.
