I have tried and tried to make Firefox work for my old eyes to no avail. Chromium is actually worse. Chrome works best for me but, but, I just used the SlackBuild for Palemoon from source. I like it so far and am gonna give it an honest try for more than a couple of hours

JWJones 12-18-2018 08:13 PM

I don't currently have it installed, but I recall qutebrowser being fairly lean on RAM.

Just an idea - Vivaldi lets you scale the entire user interface as well as the page content. Might be helpful if things are too small by default.

[ctl]+ and [ctl]- zoom the whole page in Firefox. You can increase the font size in on the menu and url bar using either a file called userChrome.css (no relation to Chrome browser) or GTK font size gtk settings. The css has the advantage of only changing Firefox. Firefox has font settings in its preferences to change font rendering size, but these don't change the UI items.

Kijiji - Follow a link and then go back and you are at the top of the page instead of where the link is. What is with that? Google-Chrome, Chromium and Vivaldi all return to the previous position on the last page.


Try and use the scroll bar and you shoot to the top (or bottom of the page). There exists no arrow at the top or bottom of the scroll bar. What is up with that? PaleMoon has no arrow but at least you can control the scroll bar.


Firefox cannot re-open a closed window and cannot re-open closed tabs after a reboot. Neither can PaleMoon. Google-Chrome and Chromium can. Vivaldi cannot re-open a closed window but it has a feature to re-open many closed tabs which is pretty nice.


Firefox, Google-Chrome, Chromium and PaleMoon all can save page specific zoom settings. Vivaldi cannot and it is real irritating.

Firefox chops the end off the date choice on the obituaries.
Past Week appears as Past Weel. A small thing but after fighting so hard with Firefox to get it to do my bidding it just bugs me to see this underline an unresolved issue.

Try and vote for a Review of any distro. Google-Chrome usually will not even allow you to because the expected button does not exist. If it does your vote is not recorded anyway so same effect. Same for Chromium while Vivaldi poses no problem. Not tried with PaleMoon yet.

The fonts are pale and washed out. Hard for my old eyes to read in any light.
ctrl and wheel just make the fonts large, pale and washed out. No joy here.

Firefox chops the numbers for the prices off at the bottom. Not so with Google-Chrome, Chromium or Vivaldi.

I force myself to use it for more than a few hours and my eyes feel like they have sand in them.
The fonts are painful and the rendering of web pages sure is a mess. The fonts on some webpages are squinty while on others they are pale and washed out. You wouldn't believe the changes and additions I have made to my system to try and solve this issue only to have it crop up over and over again. One should not be required to do so much to achieve so little and you should not have to mess with the operating system over this matter.

Chromium is impossible to get a setting that works for all websites. I ran it for years and tried everything I can think of. Messing with fonts, font size and zoom just makes you go around in circles forever.

Google-Chrome just WORKS. PaleMoon is close so far.

Memory use isn't what's draining the battery; CPU load is.

Turn off javascript and your browser should use very, very little CPU except when it is actually rendering a page. You can turn javascript back on when a page actually needs it.

Right now this laptop is running Pale Moon with 271 tabs open in six windows, and with javascript turned off it consumes about 7% CPU. When I turn javascript back on, that zips up to between 60% and 75%.

That's not Pale Moon specific, though, it should work with Firefox or Seamonkey too. I've never used Chrome, but it should work there as well.

Yep, I was wondering about all these posts regarding memory when it's CPU. My netbook has a CPU monitor which I need to look at to make sure that nothing's draining the battery since I get about 4-5 hours out of a full charge. I use Qupzilla and I'm not sure if there's a way to turn off Javascript. I don't think it's possible to install extensions from the Chrome store either.

Sorry for the misleading posts regarding memory usage, I was just curious how they stack up in that department and it was easy to measure.

CPU usage and (disk) I/O are more involved, maybe atop over a period of use:

It is also a great test of the soundness of the structure of any web site, these days most web sites fail :(.

For me, I still like Seamonkeyas it just does a few things I like better than any other browser.

In terms of memory used, here's what I got from opening each browser to the same site (here) and to this thread in a new tab (so it would be two tabs on the browser).

In no particular order:

Seamonkey - 215MB

Konqueror (also one I like, but when closed remains as a ghost app running and has to be manually disabled in ksysguard, which is what I used to see what was using what) - 153MB

Firefox (NOT the Slackware one) - 180MB

Opera Dev (latest) - More than 305MB (I didn't want to keep counting all the little 'opera' ID's down the list!)

Icecat - 304MB

Tor broswer (not Slackware one) - 367MB

Chromium (probably a pretty old version at 60.0.3112.78, I also do not like Chromium not just because of their intrusive crap, but it's just a crappy browser, IMHO) - 247MB

I don't have Vivaldi installed, and gave up long ago on Pale Moon, and just don't have the smarts to figure out how to use the browsers like Lynx and other like it. As it stands, I will keep using Seamonkey as my 'Go To', and Firefox and Opera and Tor browser every once in a while for sites where things don't work right with Seamonkey.

Oh, and this is all while using my 14.2 64bit system, not the 32bit.

This is the edit:

After 3 or 4 hours of building the latest qt5 to be able to build the falkon browser, and having built that, here is it's report:

falkon browser - 266MB

A disappointment after having done that long qt build, but oh well, no hair off my teeth, heh.

Don't underestimate the amount of battery that is drained by the screen;
Turn it less bright and see how that affects batttery drain.

Lots of white => lots of battery (as all colors have to shine bright; bit depending on the screen technology in use (LED, amoled, tft, ...)

So a darker color scheme can save much battery w/o changing applications.

Just to elaborate on this point, I recall a study which found that the biggest battery drain is between 50%-100% brightness. Under 50%, reducing brightness has negligible effects on battery life.

I think that's a feature, not a bug. There's a checkbox or something, that keeps it running by default.

Already had that in mind but trying to avoid!

are you familiar with this?

https://en.wikipedia.org/wiki/The_Ma...s_or_Minus_Two

I only exceed those limits whenever I browse a web page and I keep opening interesting links in new tabs while I stay on the page I'm looking at, but knowing I'm going to see those new tabs immediately, then close them.

Generally, I try to push this towards minimization with anything, not just browsing. For example max 3 windows for 3-way merge in a text editor.

use Opera with data saving. The real power killer is the net device.
showing used resources have nothing to do with power usage.
The display device will use more power. Turn off desktop effects.


think device not browser.
once the browser is loaded in to memory and the display has rendered it.
Then it is net device. turn off scripts.
all those options have been around a long time.
Opera has a built in adblock so you will use less net.

here is my repack read the readme
