In urma cu ceva timp scriam despre faptul ca UE a obligat Microsoftul sa le permita userilor de Windows sa opteze intre un browser sau altul.
Ei bine, azi in timpul unui update de Windows mi-a aparut imaginea de mai jos:
Ramane de vazut daca o sa ma intrebe si ce browser vreau, avand in vedere ca deja am Firefox, Iexplore, Opera si Chrome deja instalate.
Incepand din luna martie toti utilizatori de Windows XP, Vista sau Windows 7 vor avea dreptul sa aleaga ce browser folosesc. Lucrul acesta se va realiza in urma unui update, in urma caruia va rula un program care va permite sa alegi, dintr-o lista, ce browser vrei sa instalezi.
Vei putea sa instalezi unul din urmatoarele:
Apple Safari 
Mozilla Firefox 
Opera Browser 
Google Chrome 
Internet Explorer 
alte cateva browsere (de care nu a prea auzit nimeni :D).

Opera: mai multe site-uri in speed dial, cum sa cofigurezi Opera
Una din optiunile care-mi plac in browser-ul Opera, este Speed Dial, adica lista cu site-urile care apare in momentul in care deschizi un tab nou in Opera. Insa, pe masura ce folosesti aceasta optiune, constati ca ai nevoie de mai mult de 9 site-uri in Speed Dial (atat cat are by default Opera ). Pentru a mari numarul de site-uri in Speed Dial, trebuie editat fisierul “speeddial.ini” din \Documents and Settings\Numele tau\Application Data\Opera\Opera in caz ca folosesti Windows XP sau \users\numele_tau\AppData\Roaming\Opera\Opera incazul Windows Vista sau Windows 7.
Click dreapta pe speeddial.ini sau speeddial (in caz ca nu va afiseaza extensia), “open with” si selectati din fereastra care apare “Notepad”. Cauta “[Size]” si modifica dupa necesitati “rows=” si “Columns=”. Spre exemplu, eu am:
[Size]
Rows=8
Columns=6
unde rows sunt randurile, iar columns sunt coloanele. Deci am, 8 randuri si 6 coloane. Inchideti notepad-ul, iar inainte de a se inchide confirma ca esti de acord cu modificarile facute. Rezultatul este cel din imaginea de mai sus.
Download extensii google chrome, add-on-uri Chrome
Desi nu folosesc prea mult Google Chrome, trebuie sa recunosc ca acest browser are niste avantaje evidente: viteza buna de incarcare, consum de resurse mic (in comparatie cu Firefox-ul), securitate mai buna decat Iexplorer.
Si totusi, unui utilizator de Firefox, ii lipseau template-urile si add-on-urile, deci putea fi reticient in privinta trecerii “pe Chrome”. In urma cu cateva luni am constatat ca exista o groaza de teme pentru Chrome, iar mai nou, vad ca exista si un director intreg cu extensii pentru Chrome. Am vazut majoritatea extensiilor pe care le folosesc si pe Firefox. Deci, ma apuc de testat. Ramane sa vad cum se va comporta Chrome-ul dupa instalarea mai multor add-on-uri (se stie ca in cazul Firefox unele add-on-uri provoaca “crash-ul” browserului, sau duc la cresterea consumului de resurse ).
Daca se dovedeste ca Google Chrome consuma la fel de putin resurse si este la fel de stabil, dupa instalarea add-on-urilor, atunci Firefox-ul este in pericol la mine pe pc. Ma astept ca Firefox-ul sa umble la viteza de incarcare si la consumul de resurse in versiunile viitoare, pentru a nu-si pierde utilizatorii in favoare Chrome
Browserul Opera vine cu cateva noutati, cea mai importanta fiind faptul ca include un webserver. Practic, din cateva click-uri, folosindu-te de browserul Opera, poti activa un webserver prin care sa pui la dispozitia prietenilor, colegilor, familiei, cunoscutilor, acces la fisierele din pc-ul tau. Cum spuneam, din cateva click-uri poti sa creezi un mod simplu de acces la fisierele tale. Tot ce trebuie sa faci este sa-ti creezi cont pe Opera Unite , si sa vei avea o adresa de site ( vizibila pe internet ) de genul : pc-ul-tau.numele-tau.operaunite.com . Restul detaliilor le gasiti pe http://unite.opera.com si in filmul de mai jos:
Scriam de Google Chrome , cel mai nou browser web iesit pe piata. Iata ca in scurt timp au inceput sa apara si gaurile de securitate.
Attackers can combine the months-old ??ocarpet bomb??? bug with another flaw disclosed last month to trick people running Google’s brand-new Chrome browser into downloading and launching malicious code, a security researcher has warned.
The attacks are possible because Google used an older version of WebKit, the open-source rendering engine that also powers Apple’s Safari, as the foundation of Chrome, said Israeli researcher Aviv Raff on Wednesday.
Raff posted a proof-of-concept exploit to demonstrate how hackers could create a new ??oblended threat??? – so-named because it relies on multiple vulnerabilities – to attack Chrome.
??oThis is different from the Safari/IE blended threat,??? said Raff in an interview conducted via instant messaging. ??oIt’s a different blend with one similar component. It uses the auto-download vulnerability (aka ??~Carpet Bomb’) in combination with a [user interface] design flaw and an issue with Java that doesn’t display a warning on execution of JAR files downloaded from the Internet.??? Raff’s reference to the earlier Safari/IE blended threat was to his May report that said a bug in Apple’s Safari browser could be paired with an unpatched vulnerability in Microsoft’s Internet Explorer (IE) to compromise Windows PCs.The ??ocarpet bomb??? bug, revealed by researcher Nitesh Dhanjani in May and named for the way it could be used to dump files onto the Windows desktop, stemmed from the fact that Safari did not require a user’s permission to download a file. Attackers, Dhanjani said, could populate a malicious site with rogue code that Safari would automatically download to the desktop, where it might tempt a curious user into opening the file.
After first balking – for a time it refused the classify the flaw as a security vulnerability – Apple patched the bug in mid-June by updating Safari to 3.1.2.
Raff combined the still-there carpet bomb bug with another reported by UK-based penetration tester Petko Petkov at the Black Hat security conference last month. At the time, Petkov outlined how a Java flaw allows Windows to automatically execute JAR files without prompting or warning the user.
Chrome also contributes to the problem, said Raff, by making downloaded files appear as buttons at the bottom of the browser’s frame. ??oOne click on this button will execute the file,??? Raff said. Attackers could place malware on a malicious site, then wait for – or better yet, draw in – users running Chrome. The browser would not warn the user of the JAR file automatically downloaded from the site, and the button-style indicator in Chrome could be easily mistaken for part of the application.
Users can set an option in Chrome that will thwart Raff’s exploit by popping up a warning asking for a filename and location for any downloaded file. To change Chrome, select Options under the ??oCustomize and control Google Chrome??? menu; the menu is at the far right, near the top, and although not named, looks like a small wrench. Next, click the ??oMinor Tweaks??? tab in the Options window, then check the box that reads ??oAsk where to save each file before downloading.???
The blended threat, Raff argued, illustrates a bigger problem for Chrome, which has borrowed components from both Safari – via WebKit – as well as unspecified pieces of Mozilla’s open-source Firefox.
Calling the approach ??oproblematic??? from a security standpoint, Raff wondered how quickly Google will be able to patch problems in Chrome.
??oThey’ll have to track all security vulnerabilities in those [borrowed] features, and fix them in Chrome too,??? Raff said in the blog post that spelled out more detail of the Chrome/Java blended threat. ??oThis will probably be only after those vulnerabilities were fixed by the other vendors or were publicly reported. It will put Chrome users at risk for a long time.???By Gregg Keizer, Computerworld (US)
