Hello Everyone

I'm having troubles with playing some Youtube-Videos and Twitter Videos. I had to re-install my Windows 10 (64 Bit) due to some hardware-issues which are not related, and I'm having this issue since then. Here are the steps that I already did:

-Removing all Add-Ons -Starting in Safe mode - Deinstalling and reinstalling Firefox, then starting in safe Mode -Deinstalling Firefox with a tool that also deletes all Firefox-Related Registry Keys and App-Data Files and reinstalling it to a different path (other HD) -Disabling add-ons - Disabling Open264 Videocodec and widevine content decryption module (more just because of frustration^^, but I was then able to play some Youtube videos after this one) - mediasource.enabled is active (and all the other ones as well) -Installed addons (even though it didn't work with them disabled as well): NOscript( youtube videos are allowed, some of the are working), Ublock Origin, Video Download Helper, HTTPS Everyhwere, Tree Style Tab, Limit distracting sites - Updating to the newest Firefox-Version (which came out today)

Btw: on https://www.youtube.com/html5/ it tells me that everything works fine and I have of course the newest Firefox-Version installed.

Do you guys may have any other ideas?

Thank you for your help.

Kind regards,


Gabe

This seems like it should be just an annoyance, but it happens every time I open this browser and is really enough for me to move on--especially since this is an ongoing problem and I see people reporting this problem as long as two years ago. It look like a problem that no one is willing to fix.

Settings:

  • I do not have "restore previous session" so I'm not sure why it is trying to do this
  • I switched "choose what you see when you open your home page" from Firefox home to custom URL -- neither of those options helped.
  • My privacy settings are set to "delete cookies and site data" on exit.

Would also appreciate some suggestions on which browser to use next.

Thanks

I get this yellow banner at the top of page with this text, A web page is slowing...

It so far only happens when I go to my bank's website and try to sign in.

I've tried several changes to security in preferences and nothing has helped.

This only started happening on this last firefox update to 70.0.1

Now I wish I could go back to the old version, 68 something...

thanks for any help Morris

Plainly speaking, I don't like the new address bar, how it auto completes my searches or the results it pulls. I didn't like it when it was defaulted to being on starting with version 75 but I was able to easily switch a few setting in about:config to fix it. Those settings no longer affect the address bar as of update 77.

The settings I had changed were:

browser.urlbar.openViewOnFocus browser.urlbar.update1 browser.urlbar.update1.interventions browser.urlbar.update1.searchTips

which were all set to false. I saw that setting "browser.urlbar.disableExtendForTests" to "true" might be the solution but, while it does stop the address bar from expanding when using it, it also stops it from expanding at all so the websites that would come up from searching can no longer be seen either (they are still called and using the down arrow will let me scroll through the results, I just can't see any of them). It also doesn't fix the results issue which I would say is the most important.

I would like to know what I need to do so that: 1. The results it shows me are no longer based on frequent visit (basically, the pre-update search system, as is they are scattered and look messy, pulling many different sites in a seemingly random order and it's not particularly useful) 2. It no longer autocompletes results (IE. "F" autocompleting to "facebook.com", this is always something that has bothered me regardless is context) 3. It no longer pops out/expands when in use (admittedly this is mostly an aesthetic issue but I still don't like how it looks)

Web pages are loading painfully slowly, 11-34 seconds, some never load before timing out. Other browser (Edge) is loading pages quickly. Internet connection reasonably fast (35.7 Mbps). I tried the following:

  - Safe Mode, no change.
  - Refreshed Firefox, no change.
  - Disabled Antivirus and Firewall, no change.
  - Disabled Network Proxy, no change.
  - Content Process Limit set at 8.
  - Firefox is using 550 MB of memory (out of 10.2 GB)

There are instances when Firefox does load pages quickly, but they are increasingly infrequent and not predictable.

If I try to drag and drop a new bookmark onto the bookmark icon (the star with the line under it), it USED to open up Bookmarks and I could place the new bookmark where ever. That no longer works.

I CAN drag/drop into a folder on the menu bar but not into bookmarks directly.

When I try to attach a file to an email send in Gmail, nothing happens. The upload bar shows no progress and the email sits in the draft folder. The size of the file has no bearing on the problem. I've tried running in Safe Mode and even did a clean reinstall but it didn't help. The problem does not occur with the same accounts in Chrome or Opera; only in Firefox. I've tried everything recommended here, but nothing helped.

The new version of Firefox has removed the drop-down arrow from the address bar, a feature I use several times a day.

Previously, there was a way to restore this by setting a number of "browser.urlbar" options to "False." However, these are currently set at False.

Please advise. Without the drop-down arrow, Firefox is not useful at all.

Hi

I looked at a couple other threads on this problem, which said that you have to install a dictionary and (for example), "You can see which dictionary is selected if you right-click in a text area and open the Languages sub menu". But when I right click in a text area, the context menu has no mention of spelling or languages, and I can't find any place in the Options where one would install a dictionary.

Besides which, why doesn't Firefox tell the poor user that he has to install a dictionary, or put something about it by the check-box in the Options that refers to the spelling checker? And why, in the past, did I never have this problem with Firefox, but only now with a new computer? (Windows 10 as before.)

Google Maps not able to Access Location

My google maps is unable to access my location even though I have allowed location access from Firefox preferences/settings. The blue target button (Current Location) on Google maps is greyed out, and when I hover over it it says that access is not allowed. Even though when I'm in google maps, the Address bar shows that my location access is allowed, as well as in the Firefox settings. I have refreshed the window multiple times, restarted Firefox, cleared all cookies, and restarted my computer. I've also toggled the enhanced tracking protection in the address bar to off, restarted the browser, still not working. Everything in the settings tells me that access is allowed, yet google maps still tells me that it is denied. Has anyone had this problem, or know of a workaround or how to fix this? Thanks! (Working on Firefox 75. with a MAC)

Downloading and Opening docx Firefox appends doc onto file

I am using Hotdocs portal, which is an in-house document assembly tool. Firefox is the recommended browser, but it is recently handling 2016 docx files incorrectly. When we choose a file on the portal site (internal site), we go through the interview and are presented with a link to "download" the assembled file. When you click that link, a pop-up appears showing the file name as abc.docx but then says it is a Word 97 - 2003 document, even though it is not. The original template is not. If I choose to open the file, it ends up opening and showing as abc.docx.doc If I save the file, instead of opening it, it saves as abc.docx.

If we run this same process in IE/Edge, the file opens as abc.docx as it should. I have uninstalled Firefox and reinstalled. Is there anything that could be causing this? I've tried a bunch of troubleshooting steps and nothing seems to change this outcome.

Thank you.
