I am currently running Firefox version 3.6.27 under Windows 7 on a 64 bit processor. The problem is that many of the characters are superimposed making it difficult to see my work - the characters are not fuzzy but they overlap and are often not in alignment. My question is this - when will you have a release that supports Windows 7 Pro 64 bit?

Chosen solution

If you have increased the minimum font size then try the default setting "none" as a (too) high value can cause issues.

  • Tools > Options > Content : Fonts & Colors > Advanced > Minimum Font Size (none)

Make sure that you allow websites to choose their fonts.

  • Tools > Options > Content : Fonts & Colors > Advanced > [X] "Allow pages to choose their own fonts, instead of my selections above"

It is better not to increase the minimum font size, but use an extension to set the default page zoom to prevent issues with overlapping text.


Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Firefox doesnot have separate version for 64 bit but current version of Firefox should work with both 32 and 64 bit. Even i use 64bit OS.
Is it also happen on Firefox 10?


We have a Firefox version which is currently in Nightly channel and it support 64 bit but its only for experimental
