Hello :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?

The right side of screen, scroll and keys (close, minimize, etc..) on menu bar not working, any fix? When I move the entire screen leftwards, then the scroll and keys work...

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

When using built in search (google default) -- browser stops responding. Shows Firefox new tab background when loading the search. Issue resolves on Firefox close and re-open. Paste and go, creating new tabs also fail with same 'new tab background' displayed. Issue is intermittent but appears often, at least 4-5 times a day.

Tested same sample search with google chrome in same time period, no issue.

Issue appeared around the V99 update. Fix would be greatly appreciated - exiting and re-opening browser, dropping all tabs to reload is a serious usability issue.

Hi

I am using mozilla firefox on windows 10.

I sometimes fat finger ctrl+shift+w or ctrl+shift+q which closes the browser instead of just closing the tab which I indented.

Is there a way to disable these 2 key binds?

Best regards child

I'm running Firefox 100.0 (64 bit) on windows 10 pro 21H2. I've been using Firefox to access Flightradar24 to view real time flight across the globe. All of a sudden today the map doesn't appear any more . I think they use Google maps and overlay their info.

The maps show properly in MS EDGE and Google Chrome.

I've attached a screen shot of what I get.

Thanks

The browser takes extremely long time to start-up. Task manager shows that it's trying to pull some 200mbs of data at the rate of 0.5mb\s or less. RAM is fine. HDD is old, but recently defragmented and, outside of <this> particular issue - it's not a problem. System is dusty, but system is system. For some reason virtually any other program launches more or less just fine. A particularly heavy game can pull gigabytes of data in about the same time that Firefox is bottlenecked to kilobyte speed.

It's not a conflict of start-ups, I have only the driver necessities in there. it's not a windows start-up issue, the browser can take as much time even a minute after windows is loaded. It's not a (anti)virus. Because I don't use either. It's not some 15 year old Celeron trying to handle W10, FX8320 should be able to handle opening a web browser. It's not a ton of extensions, and it's not even Firefox accounting, it happened before I registered. From extensions it's only ublock origin and VPN.

My personal three guesses are:

-More than 3-5 tabs on average, but, last I checked, the tabs aren't loaded upon start-up. And power users have sessions of dozens of tabs. -100-200 bookmarks. Again, not sure how hard is it to read a text data, unless it also has to load some thumbnails or icons or whatever. -Software aging.(Latest stable firefox, updates are on, and it has been running far less than this 4 year old system)

Reinstalling the system isn't a solution. Nor is reinstalling Firefox. Nor is dumping bookmarks, because otherwise why bookmark them. I'd just like to know why is Firefox limited to kilobyte speed of initial page loading. It can't be a damaged HDD cluster, otherwise I'd feel it outside of start-up.

With my limited knowledge of PC - it's usually a random read issue. Because like every memory benchmarks(HDD and RAM) can show hysterical speeds when loading\copying some 50gigs of a single file, if it's a few hundreds of thousands of small files - it becomes random and tanks. But what I don't understand why does Firefox have THAT much clutter? Is it really the bookmarks?

Hi, I need to update my credit card details for my monthly donation to Mozilla but I cn't find out how to do it. I can't find a way from my Firefox user account to do it. Clicking on the only link I can find to Donate just throws a 403 error. Clicking on a link to help for Mozilla Donate does the same thing. Please email me advise how I can do this. Thanks, Andrew

Could you add a option of closing tab with <kbd>Ctrl</kbd>+<kbd>w</kbd> to the advanced preference?

Also, I realized that:

```browser.tabs.warnOnClose False``` Does this option activates warn when closing the tab? If your answer is yes, it is not working at all.

Hi,

There are two suggestions (or questions if I simply cannot find these): - as the default behaviour of the browser, I want to be able to only see websites from Europe. Somewhere on the net I found that the following address does it: https://www.google.com/webhp?cr=countryAT|countryBE|countryBG|countryHR|countryCY|countryCZ|countryDK|countryEE|countryFI|countryFR|countryDE|countryGR|countryHU|countryIE|countryIT|countryLV|countryLT|countryLU|countryMT|countryNL|countryPL|countryPT|countryRO|countrySK|countrySI|countryES|countrySE

However, when I am trying to use it in firefox as my Start Page, it opens all of these in separate tabs and it does not work. Also as far as I understand using the link is not possible for new tabs.

The reason is simple. For example, when looking for cooking recipes, pages from the USA use strange units that cannot be understood and there is no point in translating each of these manually as all recipes are available in million of versions - it is just a matter of clicks. But I don't want to waste time each time on checking the websites one by one; if the cooking website is from Europe, the units will be of a standard and I don't have to worry. It is the same in relation to many products of any kind. European and American markets are completely different and reading description of something only to find out at the end that it is only available in the USA is waste of time.

- it should be possible in firefox to block some websites or portals by some button. I know that there is an add-on for this but it is only for 10 pages or so, so in reality it is not very useful. It also only works in the way that the page won't open when clicked on. However, it would be much better if unwanted portals or websites were simply removed from search results.

There are too many fake websites nowadays providing incorrect or misleading information. If it happens that I come across one of these, I want to be doing that only once - and block them forever.

Despite clearing my cookies and cache, going through every step on [this web page|https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_check-browser-internals], and trying multiple different Netflix profiles, I cannot seem to get Netflix to load any content on Firefox. This problem seems to have cropped up over the last few days; I last used Netflix on June 11th and had no problems, but tried last night and again this morning to watch anything only to find that it would invariably show me a red loading wheel before presenting me with error code F7111-1105 after several minutes. This seems to be an issue with Firefox on my PC, as I have tried using the Netflix mobile app and (reluctantly) installing Chrome on my PC to test things out -- both had no problems -- yet I'm stumped! Again, I have gone through every option presented by the troubleshooting page; I have refreshed and reinstalled Firefox, made a new Firefox profile and tried it out with no extensions, scanned my PC thoroughly (with no issues presented), and nothing seems to budge.

So, despite selecting "Allow Audio and Video" in the Site Preferences, "AUTOPLAY BLOCKED" continues to show on a tab, and it only goes away once I access the tab. This particularly happens on Youtube media.

You may find attached to this question an image of my about:config settings.

What further can be done to fix this?

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 have 4 different AMD machines in a wired, Windows 7 Home network. One is a print server and has 2 Canon inkjet Printers. All machines can print to both printers from all applications except Firefox (Latest version). 1 client machine can print to both printers from Firefox, another can print to one printer and the last cannot print from Firefox at all.

I have varied the defaults and refreshed and re-installed Firefox but there is no change. The Saved Settings for printing have been cleared.

There a large number of "Modified print settings" on the machine that can print from Firefox to both printers. This setting is absent in the other machines.

Is there a way in which I can get all the 3 client machines to print from the web on both printers?

Any help would be very much appreciated.

Thanks very much, in hope

I was trying to update firefox but kept getting an error of download failed. I uninstalled firefox, but I now cannot even download the setup file, using either Google Chrome or Microsoft Edge. All I get is is an error saying "site cannot provide a secure connection" (see attached image). How can I re-install Firefox?

Why does Firefox suddenly ignore the fact that I checked the 'always ask me' box regarding where to download files and puts them in the downloads folder? this very annoying.

When I open Firefox after starting my computer, all of my tabs from the previous session are automatically restored, and they take several minutes to load. I don't have the "Open previous windows and tabs" setting enabled. Is there a way to stop Firefox from loading these tabs each time I open the browser?

I'm using Firefox 103 on KDE neon 5.25.

Hello everyone,i lost my saved datas like history,saved password etc when i changed my gmail password which i used to syc my firefox account.I wonder why it happened because i did not tick the box asking if i want to delete them.I also used another laptop to check and the data i lost in my other laptop were there.I added secondary email as back up and clicked to change the new email to primary only for me to see my data got lost from the second laptop again.why? i tried to change the password of my first primary email back to the old password but google did not allow me.My question is,can changing back to my password back to the old one bring my lost data back? i asked because that was the password used by firefox to save my data in their server.will google ever allow me to change back to old password after sometime? what i am amazed at is that i login using other browswer with the new pasword on another laptop and i got back my syc datas.Thanks in advance for your feed back.
