I was looking through the Firefox Legacy source code, and it looks like most of the fixes are for Appkit and CoreFoundation.

Non-shameful plug initiated: On these older machines running 10.7 and the like, slowdowns with Web 3.0 can sometimes be a problem, especially on iMacs or MacBook Pros.

The following has been designed to not only work well as a solution for consistent and improved performance, but for both enhanced security and user privacy, too (which commonly comes in handy, especially when given these special use cases).

Now have a question relating to the InterWeb browser which I now have up and running well on a MacMini 2,1.

Can I add the FoxPEP 2.1 file without breaking anything or rendering the browser less efficient.

You need to modify 2 settings: app.update.auto and app.update.badge (see the screenshot).

You do it by clicking on each of them: the value should change to false.

Same links as posted above or the link in my signature.

Cheers.

One related question please: As Im preparing this 2007 Mac Mini for someone else, Id like to setup the Interweb toolbar in French.

Thought this would be straightforward going into PreferencesContentLanguages-choose, adding French to the list, moving it to the top and clicking ok.

Is it possible to change the toolbar headings to French It was possible and an easy change in FireFox Legacy 67.04p1.

You can give these a try: as they are the official lang packs for Basilisk which Interweb is based on.

I gave it a try downloading and installing the fr-FR.xpi file from the link you provided.

I note however that I do have a French dictionary loaded which is at least a step in the right direction.

Whilst still on QA time, one extension Ive always like to add is Privacy Badger, and this installed ok on the FireFox Legacy browser.

Would this be a suitable add-on for additional security Although I wouldnt want to noticeably compromisedegrade the current excellent performance of Interweb.

Im going to hazard a guess that the 68.12 ESR version for Lion will work fine on Mountain Lion too.

And its the route Id recommend given the importance of security in a web browser.

Firefox Legacy 68 ESR for 10.7 and 10.8, and Firefox 78 ESR for 10.9-10.11.

Firefox 78 ESR was also updated this week.).

Have any developers considered looked at compiling a version of Firefox to use X11 (XQuartz) instead of native macOS libraries It goes without saying that Firefox natively supports X since its used on so many Linux systems, so in theory this could be a very low-maintenance way to keep the browser working and up-to-date.

As a tradeoff, it would feel someone what less mac-native, but Firefox is already so poor in that department, I dont think it would be a big loss.
