Ever since Firefox upgraded to version 75, using it has become impossible to use via RDP on Windows Server 2008 R2. The behavior is like Firefox completely hogs down the machine, but more likely seems to be impacting the refresh rate of the RDP session. With Firefox open, mouse begins to trail and button clicks and movement stack up and execute as much as a 5 minute delay at times. I saw a similar report, but not 100% the same, here: https://support.mozilla.org/en-US/questions/1278453

Here is what I know so far...

* Specific to Windows Server 2008 R2, tested on multiple VMs on multiple hosts
* Issue not present on Windows Server 2016, Windows 10, or Windows 7
* Size of Firefox window affects performance, leading to validate RDP refresh issue.  If half the screen is Firefox vs the whole screen, the lag is lessened
* Safe Mode immediately resolves the issues
* Safe Mode with all Add-Ons re-enabled still resolves the issue
* Hardware acceleration on or off has no impact
* Downgrading to Firefox 74 resolves the issue (but this could also be because it made me a new profile)

What other details can I provide? Is there anything else I can try? Does this qualify to report a bug on bugzilla?

I have my plugins synced through Firefox Sync. For development I'm using Firefox Developer Edition (FDE).

There are times I do not want to have all plugins en-/disabled in all browser. e.g. I don't need a form filler plugin all the time in my regular FF instance. But I mostly need it all day in the FDE instance.

Problem starts by disabling a plugin in the regular FF instance. Because this disables the plugin through sync in all other instances.

I'm looking for s possibility to disable plugins "locally". So only disable it for the currently running FF instance, and not propagate the state through sync.

A separate "DEV profile" might help, but I don't want to deal with sep. profiles, as the tabs would be synced in this different profile for example.

I can imagine that this is kind of an edge case scenario. But maybe somebody knows a way around this.

Can't access Wikipedia (and some other sites): “Secure Connection Failed”

Hello, everyone. My Firefox (v76.0.1, Windows 10 Pro 1909) can't access the English Wikipedia (en.wikipedia.org) and some other sites I need to work with. This started happening suddenly Tuesday night.

This is the error (in English, since my Firefox is in Brazilian Portuguese):

Secure Connection Failed

An error occurred during a connection to en.wikipedia.org. PR_END_OF_FILE_ERROR

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.

upload.wikimedia.org gives me the same error. The bizarre thing is that Wikipedias in other languages seem to work normally. Other browsers work fine.

Searching it online, it doesn't seem to be a common problem, and it just started happening by itself. I don't remember installing anything on this PC that day. My only antivirus is Windows Defender. I don't use any VPNs.

Tried all solutions I could find on Google. So far I did:

  • Ctrl + F5
  • Edited the hosts file
  • Deleted cert8.db
  • Changed network proxy settings to No proxy and Automatically detect proxy configuration (was in Use system settings)
  • Toggled DNS over HTTPS
  • Went in about:config and toggled network.dns.disableIPv6
  • Started Firefox in Safe Mode
  • Backed up the profile folder and just let Firefox create a new one
  • Rebooted my router

None of that worked.

I work with site builder platforms and since yesterday the error is starting to creep up in those servers, too.

Any ideas? I just noticed that Wikipedia search is gone from the list of opensearch engines also… This is getting increasingly bizarre…

Also, another annoying thing I noticed, `cmd+b` opens up the Bookmarks sidebar, rather than bolden the text on a WYSIWYG editor on websites (i've installed FF v76.0.1 (64-bit) on MacOS).

Hi

Is it possible to set placeholders for the Top Sites that I can define the links myself rather than pulling them from the most visited sites I've visited?

I want to hold 8 Top Links on my New Tab page but I want them to be initially blank in other words they don't go anywhere I till I click edit button.

Is this possible? Is there a way of separating the most visited sites from Top Sites buttons? Is there a way to blank all of the Top Site buttons without clearing my entire browser history?

Many thanks

In firefox, when I have to download many files at a time, I have to click one download link, wait for the modal dialog to appear, finish it and then click the next downloda link. This is very inconvenient cause I have to wait the modal dialog. In Microsoft Edge, things are different, when I click a download link, it just shows a non-modal dialog in the bottom, which I do not need to handle immediately. In this way, I can first click all the download links and then deal with all the download dialogs.(The following figure shows the behavior of microsoft edge when downloading) I prefer the behavior of Microsoft Edge, is there any way to achieve it in firefox?

I want to use Firefox as my default browser and have it installed on my laptop. My current default browser is Chrome. When I click on Firefox in the start menu, the user account control window pops up and asks if I want to allow Firefox to make changes to my computer. Click yes, and it just continues to ask if I want to make changes but never opens.

I am running Windows 10 Pro which was recently upgraded from Windows 7 Pro.

Any help would be appreciated. Thanks.

When downloading a file I always have to open it from the browser, unless it will appear as damaged. For example, after downloading a document "Study.doc" and NOT opening it from Firefox I always have two files in the Downloads folder — "Study.doc" which size is 0 kb and "Study.doc.part" which is exactly the size of the document. Therefore I cannot move it without first opening it even if I don't want to.

Attempting to seach for a bookmark (in Firefox Library) causes "not responding" message, altho search is completed in 8 minutes. Help?

Hi...Every time I attempt to search for a bookmark by clicking "show your bookmarks" (or Ctrl/shift/b), then selecting "all bookmarks", then attempting to type something in the search box, it freezes...and just allows me to press enter, it then turns the "x" in the top right red, and gives a "Not responding" message next to Library(in the top left)..I can still click the red x to cancel the search.

I say attempting to do a search, as it only allows me to type up to 4 (is the most) letters in the search box...its often just one letter before it freezes, and the curser turns into a spinning blue circle....If i just leave it for around 8 minutes,(after pressing enter) it then lists my bookmarks with the search criteria I had used, and the "Not responding" message disappears....and the machine goes back to normal

I have tried removing all my addons and extensions, tried renaming my prefs.js file, but it still hangs and takes 8 minutes.

I havent as yet done a reinstall of Firefox without any of my personal data, or tried a refresh.

The laptop is an HP i7 16gb ram, Win 10 Pro 64bit 1909, Firefox 76.0.1...with all updates present.

I've installed firefox on my new mac to match my desktop pc a little better. It works smoothly on desktop, but on this mac it seems to be nothing but trouble. Every time I reset my macbook I have to login to firefox manually, and then I'm faced with all my top sites missing. It's been mitigated slightly by adding bookmarks to my highlights page, but I'd still like to not login every time I reset. Any help would be greatly appreciated!
