Firefox Support Forum

When I look up the error message I get, everyone I see who got it can't open Firefox, but I can open it fine. For me, I have Firefox as my default browser and when another program (tModLoader on Steam) tries to open it, it gives me "Profile Missing," "Your Firefox profile cannot be loaded. It may be missing or inaccessible." I don't know if it gives the same error for other programs because I can't think of any programs that open my default browser. When I switch my default browser to Edge, the program can open Edge fine.

It's June 2022, and I am using FF64 101.0.1.

My issue is best described by Zaayl (2017) at https://support.mozilla.org/en-US/questions/1157490, but the working and easiest solution I found was the one offered by delclemons (2018) at https://support.mozilla.org/en-US/questions/1229621#question-reply.

My starting page is blank. I have an extension that shows my external IP as a country flag when FF starts up. If the flag doesn't show, I know I still cannot connect to any site. Similar to Zaayl's case, my FF can be able to connect to sites only after a certain amount of time, which varies from instant - very rarely - up to over 10 minutes. The wait always gets longer, especially when FF crashes and have to restart.

I've been searching a long, long time for the right fix. I cringe at the idea that I have to reinstall FF every time there's a major issue, like this one. Syncing back bookmarks and passwords and reinstalling the extensions are the easy part. The painful part is having to set details of accounts in the containers afterwards. I am so glad that is over now. Connection to sites is no longer prolonged after FF startup.

I wanted to thank the persons concerned, but I couldn't reply to their messages, which are now archived. So, I decided to post a new one here to do that; also, to help users who have to same issue as mine.

Currently the fonts at the top of the page (tab headers, address bar, search bar, booksmarks) are all set to a larger font. I don't know how they got changed but they are too big now. If I try change font size and style in settings nothing happens. It is not how it looked on first install and using another browser has font sizes of a more practical size. I have tried uninstalling/reinstalling Firebox and also doing a refresh and it doesn't change anything.

Its almost like a bug that has made Firefox set these fonts larger than they should and not able to modifying them again.

I cannot for the life of me work out how to fix this and its very off putting to the point, short of a full OS reinstall I'll have to start using another browser.

I would like Firefox to remember exceptions and store specific cookies that I need for the Microsoft authenticator, and other two-stage logins. Whatever setting I choose (untick delete cookiex and sitedata, assign websites to manage exceptions etc) upon closing Firefox everything is deleted, always. This means I can't use any authenticator to remember me when I want it to do so.

I used a third party cookie extension (Cookie AutoDelete) to whitelist some sites and it worked perfectly fine until an apparent recent update by Firefox. I am on Firefox 101.0.1 on Mac.

Any ideas?

Firefox not responding when I open the mobile hotspot on my laptop. I'm not sure if the problem is the program itself or windows or my laptop, but chrome seems to be working fine when I open hotspot, so I thought Firefox has something to do about it?

For more context, I don't have wifi connection in my new apartment, but I do have ethernet cable connection. That's why when I do need wifi for my phone I just open the mobile hotspot in my laptop. When I do, Firefox suddenly crashes/not responding and I have to close it. Same thing happens with discord, but I only lose connection, it doesn't crash. Sure I can use chrome, but all my bookmarks are all in firefox.

This only happened recently, June 2022. I didn't have any problem the month before, I was able to use hotspot while using Firefox at the same time.

Anyone have any idea whats the problem and/or how to fix? Thanks.

Firefox says that it is now my default browser, which is what I wanted, but my browser is still duckduckgo, and firefox browser is not on the available list of browsers to select as default. I downloaded it. I selected "make it my default browser". But it isn't. It's still duckduckgo.

I am no longer able to copy and paste an article in its original format. I no longer can copy and paste any image, including copying and pasting screenshots, without them going into attachments. I know this is not a google issue because my wife uses chrome-which I do not like-and I can copy and paste articles and images accurately on chrome. I do not wish to use chrome, or upgrade to windows 11. I have tried refreshing firefox, uninstalling and re-installing to default settings, and nothing works to restore this ability to me in firefox.

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?

When I upgrade Firefox versions, I create a new profile folder to test the newer version. When I upgraded to V101, I found Google Maps worked very well using the standard config file the install created, especially in relation to panning in Street View. then when I miggrated over my old config file from V88 Google Maps became very sluggish on panning. Clearly some config entries need tweaking. How do I know which class of config entries are used by Google Maps? I dont want to compare every single line of the config files..

Its about time Firefox came with a flyout when you hover over each config entry to tell us what it does?

Hi there,

I've searched and tried all the solutions I could find, but my FF browser still shows my timezone as Central, which is two hours ahead of my timezone, Pacific. MS Edge displays correctly, it's just FF that has the issue. There are a couple of add-ins that say they can update the timezone in FF, but not sure if I should use them (not trusted).

I verified that privacy.resistFingerprinting is set on false. Also, my control panel timezone is correct and set as Pacific, but just to see if it would correct it, I changed it and did a restart, changed it again and did a restart, and FF is still displaying Central time.

Thanks in advance for your help...

I use an addon to mute all tabs by default. The problem is that muted tabs have the MUTED text, which shrinks the size of the tab name/title. My old eyes can't deal with that very well.

Is there any way to prevent this text from showing up globally? Thanks.

This isn't a question about the "Multi-Account Containers" addons, I am pretty sure that there was a section called "Container tabs" in the privacy and security settings, and I could use containers without installing an addon some days ago.

I can still access by directly viewing this address

about:preferences#containers

But I can't find it in the settings, and this feature does no longer work.

So I went to read recent release notes from Firefox 100 to 101.0.1, but I didn't find any notes to say this feature has been disabled. Could this be an unexpected result of an update?

Years ago I imported a Firefox profile from Ubuntu 16.04 to a PC running 18.04. It wasn't very hard. View Hidden Folders, find the old FF profile, copy it. Then go to the 18.04 PC, delete or rename the existing profile, and paste in the profile from the 16.04 rig. Restart the PC, Firefox came up on the 18.04 PC just like it did on the 26.04 PC.

But Ubuntu is doing something different now. Firefox is inside the "snap" folder. Apparently snap is some sort of new package mgr. (?)

I found a firefox profile a few levels down inside the snap folder: Home/snap/firefox/common/.mozilla/firefox/xxxxxxxx.default

Does snap complicate things? Or can I replace the new profile on the 22.04 PC inside the snap folder with the profile that I want to use from the 18.04 PC? Just like in the past, but inside snap rather than the .firefox folder in Home?

"Sorry, the video player failed to load.(Error Code: 101104)" - this error message happens on some sites but not others. I believe there are more than one type of streaming transmission but do not know how to determine which is failing. For example, the streaming daily report on Democracynow.org fails while the reports on http://www.bbc.com/news/video_and_audio/international does not. This has been a problem for weeks now. I view both of these sites every day but must now use Microsoft Edge (ugh) to view democracynow.org.

Hello,

I'm using Firefox 102.0 (64-bit) on Win 10. When I click on the download icon of email attachments or Whatsapp files, firefox opens the pdf files in a new tab instead of downloading them. All other file formats are downloaded correctly instead. How can I correct this problem, please?

Best regards, Giovanni

Firefox created a second Downloads folder/library when it opens a PDF to view in the browser.

file:///C:/Users/Name/Documents/Downloads/NightSkyNotesJan2022OrionDetail.pdf

I seem to remember finding lots of temp pdfs and other files in a temp folder under user/appdata/local or roaming and having to delete this files manually from time to time. Putting the files in an easy to find folder is a good step but my Downloads Library/folder had previously been moved to D:\Downloads via choose new target from the library properties. D drive is an internal HD, C drive is an SSD. Why didn't Firefox just use the existing Downloads library instead of creating a new one on the C drive?

Ideally, if you are viewing a pdf in a Firefox tab it would delete the file if you did not download it so it does not clog up your drives. If I know i want to keep a pdf I would save to my chosen folder and view in Acrobat instead of reading in a browser tab.

I agree with a previous post i saw requesting an option for the user to specify a temp file folder on another drive when viewing pdfs to preserve some life on the SSD boot drive.

Windows 10, Firefox 101.0.1

Autofill for payment and address information has stopped working. The option to choose one will come up, but when you click it, nothing fills in. Password autofill has been working, though.

Hail all:

Now, Firefox has a very, VERY simple Bookmark Manager, that basically only allows to add, remove, and single-bookmark edit.

Now, I have for instance 6+K Youtube Links, which all, annoyingly, end with " - YouTube". I want to remove that idiocy, but to edit 6+K bookmarks, one by one?

Can you add a way to mass-edit bookmarks?

Also, can you add a "Explorer Tree Style" Bookmark manager, that shows all bookmarks in true Explorer style (As in:

All Bookmarks
--- Bookmarks Toolbar
--------- Folder 1
-------------Bookmark 1
-------------Bookmark 2
-------------Bookmark 3
------------- ...
-------- Folder 2
-------------Bookmark 1
-------------Bookmark 2
-------------  ...
--- Bookmarks Menu
--------- Folder 1
-------------Bookmark 1
-------------Bookmark 2
-------------Bookmark 3
-------------  ...
-------- Folder 2
------------ SubFolder 1
-----------------Bookmark 1
-----------------Bookmark 2
-----------------  ...
------------ SubFolder 2
-----------------Bookmark 1
-----------------Bookmark 2
-----------------  ...
-------------Bookmark 1
-------------Bookmark 2
-------------  ...
--- Other Bookmarks
--------- Folder 1
-------------Bookmark 1
-------------Bookmark 2
-------------Bookmark 3
-------------  ...
-------- Folder 2
-------------Bookmark 1
-------------Bookmark 2
-------------  ...

(without the "-" 's of course, this was my way to represent the folder and "bookmark file" system in tree form), with an option to see doubles in their respective folder/subfolder, with the normal editing functions? Since ... that would ultimately be darn helpful? Especially when implemented DIRECTLY into Firefox, so no additional tools are needed (add-ons) since these never have what I actually need.

I have a 700+ Bookmarks backup file, which says all. Far too many bookmarks to sift through, manually, without decent tools, thus the need to do it "one at a time".

Thank you very much.

Xog.
