Firefox Support Forum

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?

After update I am no longer able to open a new tab with the "add new tab"button, nor with the Ctrl + T command. A new tab will open if right clicking on a Link on page or search result and selecting/scrolling to "open in new tab". Win 7 (64bit) , FireFox Browser build 100.0(64 bit)

I recently installed Firefox 100 on Windows 7 Home Premium 64-bit (a major leap from previously installed Firefox 56).

No major squawks initially, everything was more or less as expected, but then I started to notice anomalies in the designation of visited vs. unvisited links, and possibly with clearing of history in general (see my previous question at https://support.mozilla.org/en-US/questions/1376052, still unresolved).

I'm now convinced something is definitely wrong with history clearing and/or session restores. One glaring example: Firefox 100 is overriding my choice to uncheck the "Open previous windows and tabs" box in Settings/General. The box will reset to checked after I close/relaunch Firefox, and indeed I've seen it become reset to checked in the same session, without even closing the program!

Moreover, after clearing the history prior to exiting Firefox (Shift-Ctrl-Delete, all history and data boxes checked) and then restarting Firefox, the most recently visited website will often (but not always) be restored. Remarkably, when this happens and I go to Menu/History, it shows (or claims) that history is empty!

I have tried opening About:config and setting browser.sessionstore.resume_from_crash to false, it has no effect.

This is very peculiar and disturbing, thanks for any feedback/suggestions.

Después de descargar e instalar la actualización de su navegador, la interfaz de dicho navegador solo muestra letras tan pequeñas que ni son legibles, al igual que todo lo que se busca se ve igual, y también en todas partes de su navegador esta igual de ilegibles por las minúsculas letras, ni a configuraciones puedo acceder por que no se ve nada. Pos data, ADJUNTO UN ARCHIVO DE BÚSQUEDA QUE HICE EN SU NAVEGADOR, PARA COMPROBAR LO QUE HE REDACTADO

This problem started around version 97 (i had a break from computer and went back at v 97) but older versions still had that problem after i revert to it. i did:

• turned hardware acceleration and recommended settings off
• cleared cache and profile few times
• offline and safe mode
• restarting and reinstalling for few times
• installing Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017, 2019, and 2022 (vc_redist.x64.exe).

still hangs up.

it sometimes opens after i restarted,what can cause this?

i dont have the photo right now but its like some codes that correspond in any later. of what i remember the 0 is 1 and the nomber 3 is V or N i dont remember but the 0 whas 1.

Prior to the latest update during the week of May 2, I did not have ads appear on Facebook. I have not changed any settings. After the last update, ads appear, lots of them. How can I have them omitted?

I am running Firefox 100.0. When I go to certain websites reCAPTCHA is preventing me from accessing the site. Error message: Please upgrade to a supported browser to get a reCAPTCHA challenge.

I enabled Pop-ups for those sites to no avail. Zoom.us and sedar.com are 2 websites causing problem but only on one computer.

I uninstalled and reinstalled Firefox, but no difference. I disabled Norton 360 and made no difference. No problem if I switch browser.

How do I change my "saved" email Address in your browser? It currently has my very old email address: [edited email from public] @cox.net. Many websites display that old setting associated with my info/reply. In my canned responses, I can change/update my name, phone #, etc....but cannot repeat cannot change the email address. The block displays: [edited email from public] @cox.net. I have went to settings, privacy & security, etc in your application to search how I can update this Old Email Address. Your application always sends email to my correct address: [edited email from public] @gmail.com but when I reply to the site/request my response/page displays the old incorrect email. Please Please advise how I can correct this severe problem. It prevents me from donating to viable causes/programs because my reply lists my incorrect email address.....BTW I will be most most happy to donate to you guys if we can get this error corrected. Thank You in advance for our help. Wayne Bostic, [removed phone# from public], [removed email from public]

Why do I keep getting Access Denied error messages when I try to open common sites like Lowes or Autozone? These sites have always worked with no problem for many years but now do not open. I have tried deleting all my history but they still don't work. Ready o quit FireFox.

Dear Sir.

In the search section of Firefox for a topic in Firefox right at the home page... when I type a topic to search.... it transfers my typed information to the very top of the page leaving the middle title box for search blank. I can't see what I'm typing in properly because of this...........

In Microsoft Edge this type in search works perfectly...You type it in the big search box and it then searches perfectly...and you can see better what your typing in......

In Firefox it's showing a search box to type in your information but converts it to this tiny box on top of the page.....it's terrible to use compared to Edge....

Can this be modified to work like the search page in Microsoft Edge with a Firefox update?

Thanks for your help....Leonard C.

Find the "switch" that gets "activated" (when using ANY private browser window) that prevents us from using "printscreen" AND...ALL other "printsreen apps" as well (such as "windows snipping tool"). After using ANY private browser, Printscreen just shows an all black screen! Once you've used a private browser window (on a Win 7 desktop)...you no longer have any printscreen ability until after you power-cycle...when it's too late!! Printscreen ALWAYS shows an all black screen!

Try it for yourself on YOUR desktop...regardless of your system!

AARRGGHH!! >:-(

I have two identical computers running Firefox on Windows 7. No serious issues for 3 years or longer.

Just recently, version 100 showed "Unknown Source" instead of the normal UAC authorization window which lists mozilla.org as the source.

The 100.0.1 update showed the same warning.

This only occurred on one of the computers. The other one does not show the warning.

Firefox worked fine after doing the downloads anyway, but the "Unknown Source" is not right and makes the user think security is being compromised.
