that's why I use https://addons.mozilla.org/en-US/firefox/addon/bluhell-firewall/ . imagine that it takes 136 KB only . very neat. but it is very good from mozilla to support and fix their top extensions.
ABE does nothing more than that it fully removes the "Acceptable ads" checkbox and code from ABP. I wouldn't be surprised if it had the same memory problems.
Instead of ABE, you'd do better if you just install Bluhell Firewall as u/tedshony recommended. It's so lightweight it doesn't even have any settings - just a turn on/off button (though they may add some settings in the future). And it works surprisingly well.
Honestly modern Javascript-heavy websites just kill slow CPUs, no matter what the browser is. All of the modern browsers are roughly equivalent in performance, though last I checked Firefox is the lightest in memory usage (because it doesn't have a multi-process model like Chrome).
IMHO your best bet is to keep using Firefox but use extensions to reduce the amount of Javascript it has to handle. You could go the extreme route and use NoScript to only run Javascript from sites that you whitelist, but you will need to do a lot of tweaking to get most common sites to work at all.
Ads, tracking scripts, and social network plugins on sites are usually the heaviest abusers of Javascript, so you can gain a lot of performance by blocking them. Ad Block Plus is OK, but used to be quite slow (not sure if this is still the case). uBlock Origin is much more efficient, and Bluhell Firewall is even more efficient but much more limited.
IIRC I thought youtube has always had ads like that (I know this from my friends who use chrome and constantly see them) although like you I never had many ads.
Maybe you can try having adblockers (If you don't already have them)
although right now there are issues with RAM so make sure you have some RAM to spare.
you could also try this adblocker https://addons.mozilla.org/en-US/firefox/addon/bluhell-firewall/?src=search
it seems to be more lightweight but lack features such as white listing.
A Linux distro withe a lightweight desktop or plain WM will run fine, but you won't find a browser that will both support modern websites and run well on that kind of hardware. The modern web has become incredibly resource-intensive. Even Android devices with 512MB of RAM struggle with many websites, and Android is specifically designed to run on smaller amounts of RAM.
Firefox is actually the most memory-efficient of the mainstream browsers. Ads are one of the main reasons why the web is so resource-intensive, so you can reduce its memory footprint quite a bit further by installing uBlock Origin and blocking as much content as possible. Also select the option to disable cosmetic filtering in the uBlock Origin settings to reduce the CPU requirements.
It might also be worth trying an even lighter weight ad blocker, like Bluhell Firewall. This one won't block as much content, but could be more efficient overall. You could also try NoScript, which requires a lot of manual intervention, but will greatly reduce the amount of slow Javascript that you run.
It would also be worth trying the Midori browser, but having experimented with browsers on the Raspberry Pi, it was slower and less compatible than Firefox with enough content-blocking addons.
As an alternative, even an old netbook like that would make a good dumb terminal/thin client. Just use it to access a more powerful machine over X11, NX, RDP, or whatever.
Currently I'm using Bluhell Firewall, and it seems to work great. The developer claims it not only blocks ads, but also speeds up browsing and increases privacy. That probably goes for many ad-blockers, but not all.
Nei, men jeg har gode erfaringer med de internasjonale listene. Hvis du bruker Firefox kan jeg anbefale Bluhell Firewall, den stopper stort sett alt.
Website is http://www.moneycontrol.com I noticed it is due to bluhell I disabled it and now its working fine.
I get the whole website distorted and many images don't load. You can try ones.
I've been using Minitube the Ubuntu flavor, it's very minimal/efficient for being so feature rich and it plays from the desktop.
Since I use Firefox, I've got Bluhell Firewall as my ad blocker because it's lighter weight and less intrusive than AdBlocker Plus.
