tell me whether i can find a window i closed today having multiple tabs, using "history" and recently closed tabs/windows (both). i especially want to be able to restore the tab for Institute for the Study of War and its companions. i hope you are warm and rested.

to do my regular research, i have lost three or four (or more) windows with multiple tabs, as a result of my reorganizing tabs. i think of each window with one of its tabs, so these would be, "Emma Loop" (which includes all federal court districts tabs and related info); "Kyle Griffin" (which includes various journalist/news tabs); "emptywheel" (which includes various journalist/news tabs); and other such similar windows whose name ID i don't remember.

restore scares me because it will apply to bookmarks.

i recently began migrating from twitter to mastadon, and wanted to add my regular tabs to mastadon. i moved tabs to keep track, but it seems the tab's parent windows disappeared. i cannot be more clear, because i had a total of about 15 windows with multiple tabs EACH. i regularly exited the program to install updates and because of my settings, all the windows/tabs were saved correctly. this is a great feature.

it takes time to create a window with multiple tabs, and i don't have much of a brain, so it's hard for me to learn new stuff. maybe we can work together to clarify what i need. i just want my "lost" windows/tabs to return to the others so i can continue going forward. i blame this guy - the "new twitter owner" - who has even made changes to UKRAINIANS' account performances. thank you.

When loading a page from a domain I haven't recently visited, it will almost always return the "Server Not Found - Hmm. We’re having trouble finding that site," error message. If I reload the page, however, it will load. Sometimes I have to reload 2-6 times before it works, but it always eventually succeeds. When it does work, it often times fails to load certain elements like fonts, images, embedded videos, and occasionally whole stylesheets--things that often require calls to third party domain. Again, reloading the page (sometimes multiple times) will cause the page to load properly.

I have already tried:

• Different browsers on same computer (issue does not occur)
• Firefox on different computers with different OS on same network (issue does not occur)
• Cleared cache (issue persists)
• Troubleshooting/safe mode (issue persists)
• Deleted prefs file (issue persists)
• Disabled DNS prefetching (issue persists)

'Read aloud' function: how to organize it for my html files?

In Firefox I see and can use the button 'On|Off read mode F9' on this page, where I write the question.

But when I open my page, this button is absent and F9 doesn't work. (for example, this one: http://accelerometers.000webhostapp.com/ ) Also I want to get 'Read aloud' possibility for txt files (I edited them and save as html files) What should be done to provide this possibility?

Note: in MS Edge my html files are read aloud.

Best regards, Vadim

Since changing to a new monitor and running at 1440p, the menus and url bar are in tiny mouse print. The searching I've done so far seems to point to an update removing user control to change the font size on those items. I've adjusted settings and the pages are fine, but the two things I mentioned are almost unreadable. How can I increase the font size there?

Hi,

The highlighted process sometimes goes up to as high as 55% ish CPU for hours on end, making my computer lag for no reason. If I individually close the process, nothing happens, and the issue fixes itself (firefox runs fine with it closed).

It is concerning since I could not find anything on google about this process, is this some kind of malware? I did run a MalwareBytes scan on my entire computer, and nothing turned up.

Please let me know what that process is.

Hi, I need to install a digital certificate. The instructions I have are... Tools>options>advanced>encryption>view certificates>import but I can't find anything past "tools" Thanks, Katrina

As Title,

Whenever I try to go full screen and hover to the top of the browser, It originally showed all my tabs, but recently it has not been doing that. When I hover over and over, the tabs maybe appear 10% of the time, but whenever I click somewhere else other than the Tab Bar, it disappears.

I think this bug happened ever since I enabled "Hide bookmark toolbar". I have since reverted it back, but the error is still the same. Weird, since my tabs disappear since it has nothing to do with bookmarks.

hello

1) I've been trying to change the console colours for the web developer console using userChrome.css, but I have failed. I want to set the background for console.info text to be light blue while the text color to be bold dark blue font. I would like to have it only in light theme. Also I would like to change the font size of the console for both themes.

2) Is it possible to change the folders of bookmarks to yellow. I read there are SVG. I tried to solution that are meant to change the folders to yellow, but failed. Can someone point me to a dummies guide for a solution.

The first one is the more important issue.

Thank you in advance

Please provide easy to understand explanation layman style and respective steps in easy to follow instructions in layman style how to disable all and any keyboard shortcuts in Mozilla firefox, except refresh without using cache.

i want to use only refresh without using cache to be set up with F5 key and all and any other keyboard shortcuts to be fully disabled.

Hello, Q1: Is there a way to prevent Google search engine from accessing and sharing the city I live in via my IP address?

Q2: Can I block my IP address from Amazon, Google and other shareware/spyware garbage AND still access and use the internet?

At the bottom of a Google search result page I can read the city I live in based on my IP address. I would rather not have this shared as I search for products in different stores. I am signed into Google.

When I ran the "Privacy tab" in Firefox the Google search results still showed the city I live in.

I use a VPN, three security extensions("No-Script, Privacy-Badger & FaceBook Container) and Mozilla Firefox set at the "Strict" Browser Privacy level.

Thank you for reviewing these questions, Oliver

I found a charge of $28.50 on my credit card from Saint Gervais Sur Mar with something to do with DownloadHelper. I do not remember that charge and believed it was free. How can I cancel any subscription and get money back?

I am unable to export password and logins to anywhere when I click the 3 dots its gives me the option and pop up warning but after that it goes away and does not give me the download screen to send them anywhere, running 107.0.1

I am trying to change the keyboard shortcut of the Tools → Downloads menu (opening up the downloads).

I accidentally click that sometimes and it is quite annoying, so I thought I'll switch the shortcuts to a more complex one to avoid these mistakes ^+⌘+J and when I remap that in the Keyboard preferences, the new shortcuts shows up in the menu, and it starts working but the old shortcut ⌘+J is still working.

I believe that is a bug in Firefox.

Specifically this is interesting because regular youtube content *will play just fine*

This is something I can readily reproduce for testing, diagnosis, and troubleshooting.

Please note: I have literally completed all fundamental troubleshooting several times. I respect due diligence and double checking, its just that I wish to be clear I've spent a few hours today on this and am thus far unable to impact the situation at all. --Note on Note: This includes disabling settings/features in firefox. Everything having to do with privacy, networking, hardware accel, and probably another category has been toggled multiple ways. This does not include mucking about in the detailed settings page ( about:config, etc etc). I do not memorize about:config settings I just use reference material to achieve a goal then promptly move on in life, and I am not a professional web developer though I can program so I haven't attempted to fiddle there at all. All that is to say consider any suggestions involving about:config or similar depth of settings to be *untested by myself on this matter* and therefore ripe for suggestions!

Oh, I also have not tested this in a VM. Although I certainly can if requested. I can note that a VPN does not impact this described behavior.

Well, I am able to get teh Ads to play prior to a live stream, sometimes. Note: Ads are not always displayed anyway so I cannot really know the statistics on this for sure.

At this point I have reinstalled Windows10 several times and can still reproduce this problem. All windows security settings have been toggled without impact on core issue. This has been reproduced through multiple win10 reinstalls.

Other browsers, other operating systems will function. I can use firefox on my various linux systems. I can use several versions of firefox to play these same videos on my linux systems.

However win10 at whatever patch level is unable to utilize firefox to play youtube live streams. Again, nothing I've done has impacted this behavior ( reg yt vids OK w/ preview and chats, live stream vids NOT OK, though ads and chats display fine )

I'm several varieties of engineer (Electrical, Networking, Security, Systems - whatever other varieties HR departments decide to use ) and can happily grab whatever data, or create whatever testing conditions that can be asked of me.

Thank you,

I've gone down a rabbit hole of authentication in regards to Sync with Firefox. I'm wondering if I can regenerate a recovery key by removing the recovery key from my account and then choosing to re-enable a recovery key on my account? I do have the password for my primary email on my account, but I can't find the recovery key value for it.

I also have a secondary email on my account that I don't have a password for, and need to reset a password for it, but one problem at a time...

I get this error when I try to use Firefox to get to this website "www.Fieldglass.net". I get variations when I use Edge and Chrome but it does not happen with Opera. I'd appreciate any help.

Thanks

Firefox doesn't support Netflix

Netflix worked perfectly fine on Firefox earlier in the day for me but, now, error code F7121-3078 has prevented me from accessing Netflix. I use Firefox daily so I don't want to use another browser. Help?

Hyperlinks (URLs) do not open anymore in Firefox, but do so in other browsers. I have tried many really complicated suggestions and cannot make it work. I am ready to give up.
